This is the original text the KJV's translators worked from — each Hebrew word with its own literal English meaning in this verse, prepared by scholars at Tyndale House, Cambridge. The KJV translates whole sentences, not word by word, so its wording differs: one Hebrew word can become several English words, and the KJV may choose “the LORD” where the gloss reads “Yahweh”. Both are faithful — they answer different questions. For the KJV's own rendering, switch to the KJV text.

This verse

David confesses that his sin was above all against God and done in his sight, so that God is shown to be right when he speaks and pure when he judges.

“Against thee, thee only, have I sinned,”

The doubled “thee” makes God the first party wronged. Châṭâʼ is to miss the mark, to sin.

“and done this evil in thy sight:”

Raʻ, moral wickedness, done before God’s own face. The prodigal says “in thy sight” in the same way (Luke 15:21).

“that thou mightest be justified when thou speakest,”

Tsâdaq, shown to be in the right. David’s confession agrees with every word God has said against his sin.

“and be clear when thou judgest.”

“Clear” is pure and blameless. Any judgment God brings on David is deserved.

Passage studyPsalm 51:1–6

Have Mercy upon Me, O God

1To the chief Musician, A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bathsheba. Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions. 2Wash me throughly from mine iniquity, and cleanse me from my sin. 3For I acknowledge my transgressions: and my sin is ever before me. 4Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest. 5Behold, I was shapen in iniquity; and in sin did my mother conceive me. 6Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.

Summary

David prayed this psalm after the prophet Nathan confronted him over his adultery with Bathsheba and the killing of her husband Uriah. He asks God for mercy, and the only ground he gives is God’s own lovingkindness and tender mercies. He asks God to blot out, wash and cleanse away his transgression, iniquity and sin. He owns his guilt plainly, confesses that his sin was first of all against God, and agrees that God is right to judge him. He traces his sinfulness back to his birth, and he acknowledges that God wants truth in the hidden depths of a person and will teach him wisdom there. In six verses we learn how a sinner comes back to God: honestly, leaning his whole weight on God’s mercy.

The sin behind this psalm

The heading ties the psalm to the darkest chapter of David’s life: “To the chief Musician, A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bathsheba.” 2 Samuel 11 tells how David the king took Bathsheba, the wife of Uriah, and then arranged Uriah’s death. He broke the commandments “Thou shalt not kill” and “Thou shalt not commit adultery” (Exodus 20:13–14) and abused the power God had given him. In 2 Samuel 12 God sent Nathan to him with his word, and it shattered David’s complacency. David answered, “I have sinned against the LORD” (2 Samuel 12:13), and this psalm is the prayer of that broken man.

Because of the heading, we read the psalm as the confession of a real man who had committed real and terrible sins. That is why it has become a pattern of confession for every sinner since. The man who prayed it was the one God had called “a man after his own heart” (1 Samuel 13:14, Acts 13:22). Even such a man could fall this far, and even such a fall could be brought to God.

As king, David was God’s anointed, charged with upholding God’s law and justice, and his sin dishonoured God’s name and harmed his people. Israel understood sin as an offence against God himself which also wounded the covenant community. The heading hands the psalm to the chief Musician, so the king’s confession became part of Israel’s worship, a public humbling from the highest office in the land.

Psalm 51 is one of seven psalms long known as the penitential psalms, together with Psalms 6, 32, 38, 102, 130 and 143. It follows Psalm 50, where God calls his people to worship him from the heart, above ritual, and in Psalm 51 we hear that heart in a man who has sinned. These first six verses hold David’s plea and his confession. His prayers for a clean heart and a right spirit follow (Psalm 51:7, Psalm 51:10), and the whole psalm (Psalm 51) ends in vows of service and praise and a prayer for Zion.

Mercy grounded in who God is

“Have mercy upon me, O God” asks for favour from someone who has every right to withhold it. The verb, ḥānan, is used of a gracious act by one who is greater toward one who is lower, and David, king as he is, takes the lower place and puts himself wholly in God’s hands.

He gives God one reason to hear him, and that reason is God’s own character. “According to thy lovingkindness” appeals to cheçed, God’s steadfast love, his loyal mercy and his faithfulness to his covenant. It is the love by which God keeps his commitments to his people when they fail him, so David appeals to it at the very point where he has failed most.

“According unto the multitude of thy tender mercies” adds racham, here in the plural, rachamim. The word is linked to the word for the womb, and it speaks of the deep, tender compassion a mother feels for her child. God feels for those who have sinned and answers them with tenderness. “The multitude” of these mercies tells David that God’s compassion is abundant enough for a sin as great as his.

Every true confession starts here. David brings God’s mercy before God, because forgiveness flows from who God is. Micah praises him in the same terms: “Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage?” and he goes on to say that God will cast all their sins “into the depths of the sea” (Micah 7:18–19).

Blot out my transgressions

The verb mâchâh means to wipe, erase or blot out, as writing is wiped off a surface. David asks God to wipe away the record of his transgressions so that it stands against him no longer. God promises this very thing through Isaiah, with the same picture: “I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins” (Isaiah 43:25). Through Jeremiah he says, “I will forgive their iniquity, and I will remember their sin no more” (Jeremiah 31:34).

God did forgive David, and some of the consequences of his sin still ran their course in his household, including the death of the child Bathsheba bore him (2 Samuel 12). What God blots out is the record and the guilt.

Three words for what David did

David uses three Hebrew words for his wrongdoing in these verses, and together they show the whole of his guilt.

“Transgressions” is peshaʻ, rebellion, an act by which someone defies an authority, and by extension the guilt or punishment for it. Its plural counts separate acts, so “my transgressions” are the particular deeds by which David defied God’s law and broke faith with him.

“Iniquity” is ʻâvôn. It speaks of what is crooked, twisted or perverse, a turning aside from the straight path, and it carries the guilt and the punishment that such wrongdoing deserves. It names the bent in a person from which wrong deeds come.

“Sin” is chaṭṭâʼâh, from the verb châṭâʼ, whose root sense is to miss the mark. It is falling short of what God requires, whether knowingly or unknowingly, and it can also mean the guilt of the offence. The same word is used in the law for the sin offering.

Between them these words cover David’s deliberate rebellion, the twisted heart behind it, and his failure to be what God made him to be. He names all three, and he calls each one “mine”.

Wash me throughly, and cleanse me

“Wash” is kâbaç, the word for washing clothes, which in Israel was done by treading them. “Throughly”, an older spelling of “thoroughly”, stands for râbâh, to increase or do abundantly, so the plea is “wash me much”. “Cleanse” is ṭâhêr, to be clean or pure, or to cleanse and purify. The law uses it for making a person ceremonially clean, after leprosy, after childbirth or after touching a dead body, so that he could come before God and take part in worship again. David asks for both things at once: the stain of his iniquity washed out of him, and himself made clean and fit for God’s presence.

The law gave Israel washings and sacrifices for uncleanness, and they pointed to a deeper cleansing. David uses their language and asks God himself to do the washing, because the stain has reached his inner being, where human effort cannot reach. God had promised his people this inward cleansing: “Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you” (Ezekiel 36:25). Through Isaiah he says, “though your sins be as scarlet, they shall be as white as snow” (Isaiah 1:18).

I acknowledge my transgressions

Verse 3 begins with “For”, and gives the reason for the plea of verses 1 and 2. David asks to be cleansed because he knows what he has done. “Acknowledge” is yâdaʻ, the common verb to know. David knows his transgressions as his own and owns them fully before God, taking the whole responsibility for them.

“My sin is ever before me” uses tâmîyd, continually or constantly. His sin stands in front of him wherever he looks, a weight on his conscience that he carries everywhere until God forgives him. That constant awareness is what drives him to confess.

David knew both sides of this from experience. Psalm 32 describes the time when he hid his sin: “When I kept silence, my bones waxed old through my roaring all the day long. For day and night thy hand was heavy upon me” (Psalm 32:3–4). Then it describes the relief of confession: “I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin” (Psalm 32:5).

Acknowledging sin matters because it is where repentance begins. A person who owns his sin before God agrees with God’s verdict on it and turns to him for mercy. This is the difference between sorrow over what sin has cost us and sorrow over the sin itself. Scripture puts it plainly: “He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy” (Proverbs 28:13). John gives the same promise to believers: “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness” (1 John 1:9). James adds confession to one another: “Confess your faults one to another, and pray one for another, that ye may be healed” (James 5:16).

How can my sin be ever before me without despair?

Awareness of sin is meant to lead us to God’s mercy and keep us humble, dependent on him and grateful for his grace. Conviction of this kind leads to repentance and restoration. The answer to a sin that will not leave our sight is to take it at once to the cross, where Christ has paid for it in full, and to come to God with the confidence the gospel gives: “Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need” (Hebrews 4:16).

Against thee, thee only, have I sinned

“Sinned” is châṭâʼ, the verb behind chaṭṭâʼâh. Its root sense is to miss the mark, and it means to sin, to go astray and to incur guilt. David uses it of a deliberate sin against God’s revealed will. “Evil” is raʻ, bad in both the natural and the moral sense, and here it means moral wickedness, a deed that is evil in God’s eyes and destructive in its results.

“In thy sight” means that God saw it, and more than that, that David did it before God’s own face, against his standard and his honour. The prodigal son confesses in the same words when he comes home: “Father, I have sinned against heaven, and in thy sight” (Luke 15:21). What is true of David is true of us all: “For all have sinned, and come short of the glory of God” (Romans 3:23).

Sin is so serious because God is holy. He told his people, “Ye shall be holy: for I the LORD your God am holy” (Leviticus 19:2). Repentance that sees sin as an offence against that holy God is the kind the prophets called for: “rend your heart, and not your garments, and turn unto the LORD your God” (Joel 2:13).

How could David say he sinned against God only?

David is speaking of the One whose law he broke and to whom he must answer, and the doubled “thee, thee only” makes God the first and greatest party wronged. Every moral law comes from God, so a wrong done to a neighbour is first of all a rebellion against the Lawgiver. David knew the harm he had done. The account in 2 Samuel 11 and 2 Samuel 12 sets out its cost to Bathsheba, to Uriah, to his own family and to the nation, including the death of his child and turmoil in his house. Sin always wounds people, and above that it is an offence against God, and this is the ground of true repentance. His words to Nathan put it the same way: “I have sinned against the LORD.”

That thou mightest be justified

“Justified” is tsâdaq, to be right, or to be declared right, in a moral or legal sense. Here it means that God is shown to be in the right. “Clear” means pure and blameless. “When thou speakest” and “when thou judgest” are the words of a courtroom, where a judge pronounces sentence and gives his verdict. God spoke against David’s sin in his commandments and through Nathan, and David says that every word God says against him is true and every judgment God brings on him is deserved.

God’s righteousness is already perfect, and David’s confession agrees with it openly. He is “a just God and a Saviour” (Isaiah 45:21), and David appeals to his mercy only after he has said that God is right to condemn him. That order matters. The forgiveness David asks for comes from a God whose justice stays whole.

Shapen in iniquity

“Behold” calls for attention to something sobering. David now looks past his deeds to their source. “Shapen” is chûwl. In the form used here the verb means to be brought forth or formed, so David says he was born in iniquity, ʻâvôn, the same crooked bent named in verse 2. “In sin did my mother conceive me” uses chêṭᵉʼ, from châṭâʼ, which means sin or the guilt a person bears for a wrongful act. The two lines say the same thing with growing force: from the first moment of his life, David was a sinner.

His adultery and murder, then, came from a sinful nature he had had all his life, and that is why he needs God to wash him and change him. Scripture says the same about all of us. After the flood God said that “the imagination of man’s heart is evil from his youth” (Genesis 8:21). Paul writes that “by one man sin entered into the world, and death by sin” (Romans 5:12), and that we “were by nature the children of wrath, even as others” (Ephesians 2:3).

This verse is one of the clearest statements in the Old Testament of what the church calls original sin, that we are born with a fallen nature inherited from Adam’s fall. Paul sets the teaching out fully in Romans 5:12–21. It humbles us, because it leaves us nowhere to stand but on God’s grace, and it shows how deep a cure we need.

Does this verse call conception sinful?

David is speaking about himself, and he traces his own sinfulness back to the earliest moment of his existence. The words are strong poetry, chosen to show how deep his sin goes. They accuse neither his mother nor the way God gives children. The weight falls on the fallen state into which every one of us is born.

Truth in the inward parts

“Behold” opens verse 6 as it opened verse 5. David has seen what he has been since birth, and now he sees what God wants. “Desirest” is châphêts, to be pleased with, to like or to desire. God takes pleasure in truth, and he wants it in the “inward parts”, ṭuchâh, a person’s innermost thoughts, feelings and conscience. The “hidden part”, sāṭum, is the secret core of a person that no one else can see. Together they mean that God wants honesty and integrity at the root of a person, in his motives and his character.

David had kept up appearances while hiding his sin, and he now knows that God sees through to the heart. When Samuel came to anoint David, God told him, “for man looketh on the outward appearance, but the LORD looketh on the heart” (1 Samuel 16:7). Jeremiah says that “The heart is deceitful above all things, and desperately wicked: who can know it? I the LORD search the heart, I try the reins” (Jeremiah 17:9–10). The prophets condemned worship that offered sacrifices while the heart stayed unchanged, and Isaiah tells such worshippers, “Wash you, make you clean; put away the evil of your doings from before mine eyes” (Isaiah 1:11–17).

“In the hidden part thou shalt make me to know wisdom” brings hope. “Wisdom” is chokmâh, the practical skill of living in a way that pleases God, with discernment and moral insight. God himself will teach it, in the very place where David’s falseness lay: “For the LORD giveth wisdom: out of his mouth cometh knowledge and understanding” (Proverbs 2:6). He gives it by his Spirit, by the light of his word and through the hard lessons of life, and the person who receives it lives rightly from the inside out. The God who wants truth within is the God who puts it there, and this leads straight into David’s prayer, “Create in me a clean heart, O God.”

Christ and the cleansing David asked for

Everything David asks for in these verses is given in full through Jesus Christ. John the Baptist pointed to him: “Behold the Lamb of God, which taketh away the sin of the world” (John 1:29). The blotting out David prayed for is what Christ did at the cross, “Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross” (Colossians 2:14). “For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him” (2 Corinthians 5:21).

The washing David asked for comes through Christ’s blood. The sacrifices of the law gave a cleansing that pointed ahead, for “without shedding of blood is no remission” (Hebrews 9:22), and Christ’s own blood does what they pictured: “How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?” (Hebrews 9:14). The Holy Spirit applies it to the heart “by the washing of regeneration, and renewing of the Holy Ghost” (Titus 3:5), so that Christ can “present you holy and unblameable and unreproveable in his sight” (Colossians 1:22). Anyone in Christ “is a new creature” (2 Corinthians 5:17).

David confessed that God is just when he judges. At the cross God showed his justice and his mercy together, “that he might be just, and the justifier of him which believeth in Jesus” (Romans 3:26). The new heart David longed for is the gift of the new covenant: “A new heart also will I give you, and a new spirit will I put within you” (Ezekiel 36:26), with God’s Spirit within causing his people to walk in his statutes (Ezekiel 36:26–27).

David was conceived in sin, and Jesus was conceived by the Holy Ghost, “that holy thing” born of Mary (Luke 1:35). He was “in all points tempted like as we are, yet without sin” (Hebrews 4:15). He deals with the root of sin that David confessed, and he gives a new birth: “Except a man be born again, he cannot see the kingdom of God” (John 3:3).

Christ alone had truth in his inward parts perfectly, and he exposed those who kept up an outward show over a corrupt heart. He said they were “like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men’s bones” (Matthew 23:27). He taught that “out of the heart proceed evil thoughts” (Matthew 15:19) and that “Blessed are the pure in heart: for they shall see God” (Matthew 5:8). The wisdom David asked for is found in him, “In whom are hid all the treasures of wisdom and knowledge” (Colossians 2:3), for Christ “of God is made unto us wisdom” (1 Corinthians 1:30). His Spirit teaches us all things (John 14:26) and guides us into all truth (John 16:13).

Coming back to God after sin

David’s sin was about as grievous as sin can be, and he still found mercy. Whatever you have done, you can come to God the way he did, asking for mercy on the ground of God’s lovingkindness and the multitude of his tender mercies, and trusting him to blot out and wash away what you cannot.

His prayer belongs to Christians as much as it belonged to him. Believers are declared righteous in Christ and secure in him, and sin still clings to us, so we keep confessing and keep being cleansed while God goes on making us holy. The promise of 1 John 1:9 is written to people who already belong to God.

These verses also show how to confess. Call your sin what God calls it, own it as yours, agree that God is right about it, and let him see the heart behind it. He takes pleasure in truth in the inward parts, and in that hidden place he will teach you wisdom.

I. II. Main points1. 2. Sub-points(1.) (2.) Details[1.] [2.] Fine details

The title has reference to a very sad story, that of David's fall. But, though he fell, he was not utterly cast down, for God graciously upheld him and raised him up. 1. The sin which, in this psalm, he laments, was the folly and wickedness he committed with his neighbour's wife, a sin not to be spoken of, nor thought of, without detestation. His debauching of Bathsheba was the inlet to all the other sins that followed; it was as the letting forth of water. This sin of David's is recorded for warning to all, that he who thinks he stands may take heed lest he fall. 2. The repentance which, in this psalm, he expresses, he was brought to by the ministry of Nathan, who was sent of God to convince him of his sin, after he had continued above nine months (for aught that appears) without any particular expressions of remorse and sorrow for it. But though God may suffer his people to fall into sin, and to lie a great while in it, yet he will, by some means or other, recover them to repentance, bring them to himself and to their right mind again. Herein, generally, he uses the ministry of the word, which yet he is not tied to. But those that have been overtaken in any fault ought to reckon a faithful reproof the greatest kindness that can be don them and a wise reprover their best friend. Let the righteous smite me, and it shall be excellent oil. 3. David, being convinced of his sin, poured out his soul to God in prayer for mercy and grace. Whither should backsliding children return, but to the Lord their God, from whom they have backslidden, and who alone can heal their backslidings? 4. He drew up, by divine inspiration, the workings of his heart towards God, upon this occasion, into a psalm, that it might be often repeated, and long after reviewed; and this he committed to the chief musician, to be sung in the public service of the church. (1.) As a profession of his own repentance, which he would have to be generally taken notice of, his sin having been notorious, that the plaster might be as wide as the wound. Those that truly repent of their sins will not be ashamed to own their repentance; but, having lost the honour of innocents, they will rather covet the honour of penitents. (2.) As a pattern to others, both to bring them to repentance by his example and to instruct them in their repentance what to do an what to say. Being converted himself, he thus strengthens his brethren (Luke 22:32), and for this cause he obtained mercy, 1 Timothy 1:16.

In these words we have,

I.David's humble petition, Psalm 51:1, Psalm 51:2.

His prayer is much the same with that which our Saviour puts into the mouth of his penitent publican in the parable: God be merciful to me a sinner! Luke 18:13. David was, upon many accounts, a man of great merit; he had not only done much, but suffered much, in the cause of God; and yet, when he is convinced of sin, he does not offer to balance his evil deeds with his good deeds, nor can he think that his services will atone for his offences; but he flies to God's infinite mercy, and depends upon that only for pardon and peace: Have mercy upon me, O God! He owns himself obnoxious to God's justice, and therefore casts himself upon his mercy; and it is certain that the best man in the world will be undone if God be not merciful to him. Observe,

1.What his plea is for this mercy: "have mercy upon me, O God! not according to the dignity of my birth, as descended from the prince of the tribe of Judah, not according to my public services as Israel's champion, or my public honours as Israel's king;" his plea is not, Lord, remember David and all his afflictions, how he vowed to build a place for the ark (Psalm 132:1, Psalm 132:2); a true penitent will make no mention of any such thing; but "Have mercy upon me for mercy's sake. I have nothing to plead with thee but," (1.) "The freeness of thy mercy, according to thy lovingkindness, thy clemency, the goodness of thy nature, which inclines thee to pity the miserable." (2.) "The fulness of thy mercy. There are in thee not only lovingkindness and tender mercies, but abundance of them, a multitude of tender mercies for the forgiveness of many sinners, of many sins, to multiply pardons as we multiply transgressions."

2.What is the particular mercy that he begs - the pardon of sin. Blot out my transgressions, as a debt is blotted or crossed out of the book, when either the debtor has paid it or the creditor has remitted it. "Wipe out my transgressions, that they may not appear to demand judgment against me, nor stare me in the face to my confusion and terror." The blood of Christ, sprinkled upon the conscience, to purify and pacify that, blots out the transgression, and, having reconciled us to God, reconciles up to ourselves, Psalm 51:2. "Wash me thoroughly from my iniquity; wash my soul from the guilt and stain of my sin by thy mercy and grace, for it is only from a ceremonial pollution that the water of separation will avail to cleanse me. Multiple to wash me; the stain is deep, for I have lain long soaking in the guilt, so that it will not easily be got out. O wash me much, wash me thoroughly. Cleanse me from my sin." Sin defiles us, renders us odious in the sight of the holy God, and uneasy to ourselves; it unfits us for communion with God in grace or glory. When God pardons sin he cleanses us from it, so that we become acceptable to him, easy to ourselves, and have liberty of access to him. Nathan had assured David, upon his first profession of repentance, that his win was pardoned. The Lord has taken away thy sin; thou shalt not die, 2 Samuel 12:13. Yet he prays, Wash me, cleanse, blot out my transgressions; for God will be sought unto even for that which he has promised; and those whose sins are pardoned must pray that the pardon may be more and more cleared up to them. God had forgiven him, but he could not forgive himself; and therefore he is thus importunate for pardon, as one that thought himself unworthy of it and knew how to value it.

II.David's penitential confessions, Psalm 51:3-5.

1.He was very free to own his guilt before God: I acknowledge my transgressions; this he had formerly found the only way of easing his conscience, Psalm 32:4, Psalm 32:5. Nathan said, Thou art the man. I am, says David; I have sinned.

2.He had such a deep sense of it that the was continually thinking of it with sorrow and shame. His contrition for his sin was not a slight sudden passion, but an abiding grief: "My sin is ever before me, to humble me and mortify me, and make me continually blush and tremble. It is ever against me" (so some); "I see it before me as an enemy, accusing and threatening me." David was, upon all occasions, put in mid of his sin, and was willing to be so, for his further abasement. He never walked on the roof of his house without a penitent reflection on his unhappy walk there when thence he saw Bathsheba; he never lay down to sleep without a sorrowful thought of the bed of his uncleanness, never sat down to meat, never sent his servant on an errand, or took his pen in hand, but it put him in mind of his making Uriah drunk, the treacherous message he sent by him, and the fatal warrant he wrote and signed for his execution. Note, The acts of repentance, even for the same sin, must be often repeated. It will be of good use for us to have our sins ever before us, that by the remembrance of our past sins we may be kept humble, may be armed against temptation, quickened to duty, and made patient under the cross.

(1.)He confesses his actual transgressions (Psalm 51:4): Against thee, thee only, have I sinned. David was a very great man, and yet, having done amiss, submits to the discipline of a penitent, and thinks not his royal dignity will excuse him from it. Rich and poor must here meet together; there is one law of repentance for both; the greatest must be judged shortly, and therefore must judge themselves now. David was a very good man, and yet, having sinned, he willingly accommodates himself to the place and posture of a penitent. The best men, if they sin, should give the best example of repentance.

[1.]His confession is particular; "I have done this evil, this that I am now reproved for, this that my own conscience now upbraids me with." Note, It is good to be particular in the confession of sin, that we may be the more express in praying for pardon, and so may have the more comfort in it. We ought to reflect upon the particular heads of our sins of infirmity and the particular circumstances of our gross sins.

[2.]He aggravates the sin which he confesses and lays a load upon himself for it: Against thee, and in thy sight. Hence our Saviour seems to borrow the confession which he puts into the mouth of the returning prodigal: I have sinned against heaven, and before thee, Luke 15:18. Two things David laments in his sin: - First, That it was committed against God. To him the affront is given, and he is the party wronged. It is his truth that by wilful sin we deny, his conduct that we despise, his command that we disobey, his promise that we distrust, his name that we dishonour, and it is with him that we deal deceitfully and disingenuously. From this topic Joseph fetched the great argument against sin (Genesis 39:9), and David here the great aggravation of it: Against thee only. Some make this to intimate the prerogative of his crown, that, as a king, he was not accountable to any but God; but it is more agreeable to his present temper to suppose that it expresses the deep contrition of his soul for his sin, and that it was upon right grounds. He here sinned against Bathsheba and Uriah, against his own soul, and body, and family, against his kingdom, and against the church of God, and all this helped to humble him; but none of these were sinned against so as God was, and therefore this he lays the most sorrowful accent upon: Against thee only have I sinned. Secondly, That it was committed in God's sight. "This not only proves it upon me, but renders it exceedingly sinful." This should greatly humble us for all our sins, that they have been committed under the eye of God, which argues either a disbelief of his omniscience or a contempt of his justice.

[3.]He justifies God in the sentence passed upon him - that the sword should never depart from his house, 2 Samuel 12:10, 2 Samuel 12:11. He is very forward to own his sin, and aggravate it, not only that he might obtain the pardon of it himself, but that by his confession he might give honour to God. First, That God might be justified in the threatenings he had spoken by Nathan. "Lord, I have nothing to say against the justice of them; I deserve what is threatened, and a thousand times worse." Thus Eli acquiesced in the like threatenings (1 Samuel 3:18), It is the Lord. And Hezekiah (2 Kings 20:19), Good is the word of the Lord, which thou hast spoken. Secondly, That God might be clear when he judged, that is, when he executed those threatenings. David published his confession of sin that when hereafter he should come into trouble none might say God had done him any wrong; for he owns the Lord is righteous: thus will all true penitents justify God by condemning themselves. Thou art just in all that is brought upon us.

(2.)He confesses his original corruption (Psalm 51:5): Behold, I was shapen in iniquity. He does not call upon God to behold it, but upon himself. "Come, my soul, look unto the rock out of which I was hewn, and thou wilt find I was shapen in iniquity. Had I duly considered this before, I find I should not have made so bold with the temptation, nor have ventured among the sparks with such tinder in my heart; and so the sin might have been prevented. Let me consider it now, not to excuse or extenuate the sin - Lord, I did so; but indeed I could not help it, my inclination led me to it" (for as that plea is false, with due care and watchfulness, and improvement of the grace of God, he might have helped it, so it is what a true penitent never offers to put in), "but let me consider it rather as an aggravation of the sin: Lord, I have not only been guilty of adultery and murder, but I have an adulterous murderous nature; therefore I abhor myself." David elsewhere speaks of the admirable structure of his body (Psalm 139:14, Psalm 139:15); it was curiously wrought; and yet here he says it was shapen in iniquity, sin was twisted in with it; not as it came out of God's hands, but as it comes through our parents' loins. He elsewhere speaks of the piety of his mother, that she was God's handmaid, and he pleads his relation to her (Psalm 116:16, Psalm 86:16), and yet here he says she conceived him in sin; for though she was, by grace, a child of God, she was, by nature, a daughter of Eve, and not excepted from the common character. Note, It is to be sadly lamented by every one of us that we brought into the world with us a corrupt nature, wretchedly degenerated from its primitive purity and rectitude; we have from our birth the snares of sin in our bodies, the seeds of sin in our souls, and a stain of sin upon both. This is what we call original sin, because it is as ancient as our original, and because it is the original of all our actual transgressions. This is that foolishness which is bound in the heart of a child, that proneness of evil and backwardness to good which is the burden of the regenerate and the ruin of the unregenerate; it is a bent to backslide from God.

III.David's acknowledgment of the grace of God (Psalm 51:6), both his good-will towards us ("thou desirest truth in the inward parts, thou wouldst have us all honest and sincere, and true to our profession") and his good work in us - "In the hidden part thou hast made," or shalt make, "me to know wisdom." Note,

1.Truth and wisdom will go very far towards making a man a good man. A clear head and a sound heart (prudence and sincerity) bespeak the man of God perfect.

2.What God requires of us he himself works in us, and he works it in the regular way, enlightening the mind, and so gaining the will. But how does this come in here? (1.) God is hereby justified and cleared: "Lord, thou was not the author of my sin; there is no blame to be laid upon thee; but I alone must bear it; for thou has many a time admonished me to be sincere, and hast made me to know that which, if I had duly considered it, would have prevented my falling into this sin; had I improved the grace thou hast given me, I should have kept my integrity." (2.) The sin is hereby aggravated: "Lord, thou desirest truth; but where was it when I dissembled with Uriah? Thou hast made me to know wisdom; but I have not lived up to what I have known." (3.) He is hereby encouraged, in his repentance, to hope that God would graciously accept him; for, [1.] God had made him sincere in his resolutions never to return to folly again: Thou desirest truth in the inward part; this is that which God has an eye to in a returning sinner, that in his spirit there be no guile, Psalm 32:2. David was conscious to himself of the uprightness of his heart towards God in his repentance, and therefore doubted not but God would accept him. [2.] He hoped that God would enable him to make good his resolutions, that in the hidden part, in the new man, which is called the hidden man of the heart (1 Peter 3:4), he would make him to know wisdom, so as to discern and avoid the designs of the tempter another time. Some read it as a prayer: "Lord, in this instance, I have done foolishly; for the future make me to know wisdom." Where there is truth God will give wisdom; those that sincerely endeavour to do their duty shall be taught their duty.

d. AD 56Romanson 3:1-8Ante-Nicene
What advantage then hath the Jew? or what profit is there of circumcision? Much every way: chiefly, because that unto them were committed the oracles of God. For what if some did not believe? shall their unbelief make the faith of God without effect? God forbid: yea, let God be true, but every man a liar; as it is written, That thou mightest be justified in thy sayings, and mightest overcome when thou art judged. [Psalm 51:4] But if our unrighteousness commend the righteousness of God, what shall we say? Is God unrighteous who taketh vengeance? (I speak as a man) God forbid: for then how shall God judge the world? For if the truth of God hath more abounded through my lie unto his glory; why yet am I also judged as a sinner? And not rather, (as we be slanderously reported, and as some affirm that we say,) Let us do evil, that good may come? whose damnation is just.
d. AD 348Pachomius the GreatPost-NiceneSourcePARALIPOMENA 8:14
As the holy old man Pachomius was journeying to his own monastery and had come near the desert called Amnon, legions of demons rose both on his right hand and on his left, some following him and others running in front of him, saying, “Behold the blessed man of God.” They were doing this, wishing to sow vainglory in him. But he knew their cunning, and the more they shouted, the more he cried out to God, confessing his sins. And undoing the demons’ cunning, he spoke out to them, saying, “O wicked ones! You cannot carry me away with you into vainglory, for I know my failures, for which I ought to weep constantly over eternal punishment. I have therefore no need of your false speech and guileful deceit, for your work is the destruction of the soul. And I am not carried away by your praises, for I know the cunning of your unholy minds.” And although holy Pachomius said these things to them, they did not stop their shamelessness; they followed alongside the blessed man until he drew near his monastery.
“I [the prodigal son] have sinned,” he says, “against heaven and before you.” He confesses what is clearly a sin to death, that you may not think that any one doing penance is rightly shut out from pardon. For one who has sinned against heaven has sinned either against the kingdom of heaven or against his own soul, which is a sin to death, and against God, to whom alone is said: “Against you only have I sinned and done evil before you.”
d. AD 407John ChrysostomPost-NiceneSourceON THE EPISTLE TO THE HEBREWS 32:3
Beloved, let us praise her, through whom we have been saved. Let us love her; let us prefer her to wealth. Let us have a merciful soul apart from wealth. Nothing is more characteristic of a Christian than mercy. There is nothing that unbelievers and all people are so amazed at as when we are merciful. For we ourselves are often in need of this mercy and say to God, “Have mercy on us according to the greatness of your mercy.” Let us begin first ourselves; yet we do not begin first. For he has already shown his mercy that he has toward us. But, beloved, let us follow second. For if people have mercy on one who was merciful, even if he has committed countless sins, God is much more merciful.
d. AD 420JeromePost-NiceneSourceLETTER 122.3
Psalm 50 [51] shows the complete repentance of a sinner when David, who had gone into Bathsheba, the wife of Uriah the Hittite and was rebuked by the prophet Nathan, said, “I have sinned.” Immediately he deserved to hear “The Lord has removed your sin from you.” For he, who had added homicide to adultery and was moved to tears, said, “God, have compassion on me according to your great pity, and according to the multitude of your mercies take away my iniquity.” Since a great sin needed great mercy, he added, “Wash me completely from my iniquity, and my offense is always before me. I have sinned against you only”—for a king did not fear anyone else—“and I have done evil in your sight so that you will be justified in your speaking and you overcome when you judge.” “For God has included all things under sin so that he may be merciful to all.” He made so much progress that he who a little earlier had been a penitent sinner became a master and was able to say, “I will teach the unjust your ways, and sinners will be converted to you.” Since confession and beauty are before God, the one who confesses his sins and says, “My wounds have been destroyed and become putrefied,” changes the foulness of his wounds into a healthy state. But “he who hides his sins will not prosper.”
"Against You alone have I sinned, and before You an evil thing have I done" [Psalm 51:4]. What is this? For before men was not another's wife debauched and husband slain? Did not all men know what David had done? [2 Samuel 11:4, 15] What is, "Against You alone have I sinned, and before You an evil thing have I done." Because You alone are without sin. He is a just punisher that has nothing in Him to be punished; He is a just reprover that has nothing in Him to be reproved. "That you may be justified in Your sayings, and conquer when You are judged." To whom he speaks, brethren, to whom he speaks, is difficult to understand. To God surely he speaks, and it is evident that God the Father is not judged. What is, "And conquer when You are judged"? He sees the future Judge to be judged, one just by sinners to be judged, and therein conquering, because in Him was nothing to be judged. For alone among men could truly say the God-Man, "If you have found in Me sin, say." [John 8:46] But perchance there was what escaped men, and they found not what was really there, but was not manifest. In another place [John 14:30] He says, "Behold there comes the Prince of the world," being an acute observer of all sins; "Behold," He says, "there comes the Prince of this world," with death afflicting sinners, presiding over death: for, "By the malice of the devil death came into the world." [Wisdom 2:24] "Behold," He says, "there comes the Prince of the world:"— He said these words close upon His Passion:— "and in Me he shall find nothing," nothing of sin, nothing worthy of death, nothing worthy of condemnation. And as if it were said to Him, Why then do You die? He continues and says, "But that all men may know that I do the will of My Father; arise, let us go hence." I suffer, He says, undeserving, for men deserving, in order that them I may make deserving of My Life, for whom I undeservedly suffer their death. To Him then, having no sin, says on the present occasion the Prophet David, "Against You only have I sinned, and before You an evil thing have I done, that You may be justified in Your sayings, and conquer when You are judged." For Thou overcomest all men, all judges; and he that deems himself just, before You is unjust: Thou alone justly judgest, having been unjustly judged, That hast power to lay down Your life, and hast power again to take it. [John 10:18] Thou conquerest, then, when You are judged. All men Thou overcomest, because You are more than men, and by You were men made.
Some monks called Euchites, or “men of prayer,” once came to Abba Lucius in the ninth region of Alexandria. And the old man asked them, “What work do you do with your hands?” And they said, “We do not work with our hands. We obey St. Paul’s command and pray without ceasing.” The old man said to them, “Do you not eat?” They said, “Yes, we eat.” And the old man said to them, “When you are eating, who prays for you?” Again, he asked them, “Do you not sleep?” They said, “We sleep.” And the old man said, “Who prays for you while you are asleep?” They would not answer him. And he said to them, “Forgive me, brothers, but you do not practice what you say. I will show you how I pray without ceasing though I work with my hands. With God’s help, I sit and collect a few palm leaves, and interweave them and say, ‘Have mercy on me, O God, according to your great mercy: and according to the multitude of your mercies do away with my iniquity.’ ” And he said to them, “Is that prayer, or is it not?” They said, “It is prayer.”
d. AD 533Fulgentius of RuspePost-NiceneSourceON THE FORGIVENESS OF SINS 1:12.3
Finally, holy David successfully gained divine mercy because, having been converted by the humility of a contrite heart, he condemned the evil he had done by acknowledging it and did not put off punishment by doing penance for the lust of the evil deed he had fallen into; because, if he had not punished the cause of the guilt in which he was held, without a doubt he would have been punished. Having been converted to penance, he acknowledged his crime, fearing lest he would have to acknowledge the penalty by being condemned. By doing penance, he punished himself by acknowledging what he wanted to be overlooked by the Lord in himself. Finally, since he said, “Have mercy on me, O God, according to your steadfast love; according to your abundant mercy blot out my transgressions. Wash me thoroughly from my iniquity, and cleanse me from my sin.” Immediately following this he added, “For I know my transgressions, and my sin is ever before me.” He acknowledged his sin, not that by sinning he might increase it the more, but that by repenting, he might wash it away; and so the domination of sin, which blameworthy enjoyment had brought in, true conversion removed. And because David, converted with all his heart, groaned, he was immediately saved and thus in him was fulfilled what is commanded through the prophet: “If you are converted and groan, you will be saved.”
d. AD 585CassiodorusPost-NiceneSourceEXPOSITIONS OF THE PSALMS 18:13
“Who can understand his sins? Cleanse me from my hidden faults, O Lord.” See, the door of the third section opens, in which the prophet implores that all his sins would be washed away until the eloquence of his mouth would be rendered acceptable in the sight of the Lord. But because transgressions occur by means of human errors in three manners—thought, word and deed—he attests that that immense sea of sins, condensed in brevity, originates from two sources. The “hidden” sin is that which is called “original,” in which we are conceived, born and sin by a secret will, such as when we covet our neighbor’s property, when we desire to take vengeance on our enemies, when we want to be exalted above others, when we seek after tastier foods, and do things similar to these things. They sprout up and quietly seize us in such a way that they seem to be hidden to many until the deed is done. But if these things should be rendered visible to someone—as Solomon warns, “Do not go after your evil desires”20—we nonetheless ought to notice that there are many sins which we altogether do not know, of which we are able to understand neither their origins nor their manners of snatching us away. One must understand the phrase “Who understands all his sins?” from this perspective, because when he will go on to say in Psalm 51, “My sin is always before me” and elsewhere, “I have made my sin known to you,” how can it not be understood that whenever he sins he is compelled to confess? But if you add the word “all,” then this objection is shown to be obviated.
