Commentary on Psalms 51 verses 7–13
I. See here what David prays for. Many excellent petitions he here puts up, to which if we do but add, "for Christ's sake," they are as evangelical as any other.
1.He prays that God would cleanse him from his sins and the defilement he had contracted by them (Psa 51:7): "Purge me with hyssop; that is, pardon my sins, and let me know that they are pardoned, that I may be restored to those privileges which by sin I have forfeited and lost." The expression here alludes to a ceremonial distinction, that of cleansing the leper, or those that were unclean by the touch of a body by sprinkling water, or blood, or both upon them with a bunch of hyssop, by which they were, at length, discharged from the restraints they were laid under by their pollution. "Lord, let me be as well assured of my restoration to thy favour, and to the privilege of communion with thee, as they were thereby assured of their re-admission to their former privileges." But it is founded upon gospel-grace: Purge me with hyssop, that is, with the blood of Christ applied to my soul by a lively faith, as water of purification was sprinkled with a bunch of hyssop. It is the blood of Christ (which is therefore called the blood of sprinkling, Heb 12:24), that purges the conscience from dead works, from that guilt of sin and dread of God which shut us out of communion with him, as the touch of a dead body, under the law, shut a man out from the courts of God's house. If this blood of Christ, which cleanses from all sin, cleanse us from our sin, then we shall be clean indeed, Heb 10:2. If we be washed in this fountain opened, we shall be whiter than snow, not only acquitted but accepted; so those are that are justified. Isa 1:18, Though your sins have been as scarlet, they shall be white as snow.
2.He prays that, his sins being pardoned, he might have the comfort of that pardon. He asks not to be comforted till first he is cleansed; but if sin, the bitter root of sorrow, be taken away, he can pray in faith, "Make me to hear joy and gladness (Psa 51:8), that is, let me have a well-grounded peace, of thy creating, thy speaking, so that the bones which thou hast broken by convictions and threatenings may rejoice, may not only be set again, and eased from the pain, but may be sensibly comforted, and, as the prophet speaks, may flourish as a herb." Note, (1.) The pain of a heart truly broken for sin may well be compared to that of a broken bone; and it is the same Spirit who as a Spirit of bondage smites and wounds and as a Spirit of adoption heals and binds up. (2.) The comfort and joy that arise from a sealed pardon to a penitent sinner are as refreshing as perfect ease from the most exquisite pain. (3.) It is God's work, not only to speak this joy and gladness, but to make us hear it and take the comfort of it. He earnestly desires that God would lift up the light of his countenance upon him, and so put gladness into his heart, that he would not only be reconciled to him, but, which is a further act of grace, let him know that he was so.
3.He prays for a complete and effectual pardon. This is that which he is most earnest for as the foundation of his comfort (Psa 51:9): "Hide thy face from my sins, that is, be not provoked by them to deal with me as I deserve; they are ever before me, let them be cast behind thy back. Blot out all my iniquities out of the book of thy account; blot them out, as a cloud is blotted out and dispelled by the beams of the sun," Isa 44:22.
4.He prays for sanctifying grace; and this every true penitent is as earnest for as for pardon and peace, Psa 51:10. He does not pray, "Lord, preserve me my reputation," as Saul, I have sinned, yet honour me before this people. No; his great concern is to get his corrupt nature changed: the sin he had been guilty of was, (1.) An evidence of its impurity, and therefore he prays, Create in me a clean heart, O God! He now saw, more than ever, what an unclean heart he had, and sadly laments it, but sees it is not in his own power to amend it, and therefore begs of God (whose prerogative it is to create) that he would create in him a clean heart. He only that made the heart can new-make it; and to his power nothing is impossible. He created the world by the word of his power as the God of nature, and it is by the word of his power as the God of grace that we are clean (Joh 15:3), that we are sanctified, Joh 17:17. (2.) It was the cause of its disorder, and undid much of the good work that had been wrought in him; and therefore he prays, "Lord, renew a right spirit within me; repair the decays of spiritual strength which this sin has been the cause of, and set me to rights again." Renew a constant spirit within me, so some. He had, in this matter, discovered much inconstancy and inconsistency with himself, and therefore he prays, "Lord, fix me for the time to come, that I may never in like manner depart from thee."
5.He prays for the continuance of God's good-will towards him and the progress of his good work in him, Psa 51:11. (1.) That he might never be shut out from God's favour: "Cast me not away from thy presence, as one whom thou abhorrest and canst not endure to look upon." He prays that he might not be thrown out of God's protection, but that wherever he went, he might have the divine presence with him, might be under the guidance of his wisdom and in the custody of his power, and that he might not be forbidden communion with God: "Let me not be banished thy courts, but always have liberty of access to thee by prayer." He does not deprecate the temporal judgments which God by Nathan had threatened to bring upon him. "God's will be done; but, Lord, rebuke me no in thy wrath. If the sword come into my house never to depart from it, yet let me have a God to go to in my distresses, and all shall be well." (2.) That he might never be deprived of God's grace: Take not thy Holy Spirit from me. He knew he had by his sin grieved the Spirit and provoked him to with draw, and that because he also was flesh God might justly have said that his Spirit should no more strive with him nor work upon him, Gen 6:3. This he dreads more than any thing. We are undone if God take his Holy Spirit from us. Saul was a sad instance of this. How exceedingly sinful, how exceedingly miserable, was he, when the Spirit of the Lord had departed from him! David knew it, and therefore begs thus earnestly: "Lord, whatever thou take from me, my children, my crown, my life, yet take not thy Holy Spirit from me" (see Sa2 7:15), "but continue thy Holy Spirit with me, to perfect the work of my repentance, to prevent my relapse into sin, and to enable me to discharge my duty both as a prince and as a psalmist."
6.He prays for the restoration of divine comforts and the perpetual communications of divine grace, Psa 51:12. David finds two ill effects of his sin: - (1.) It had made him sad, and therefore he prays, Restore unto me the joy of thy salvation. A child of God knows no true nor solid joy but the joy of God's salvation, joy in God his Saviour and in the hope of eternal life. By wilful sin we forfeit this joy and deprive ourselves of it; our evidences cannot but be clouded and our hopes shaken. When we give ourselves so much cause to doubt of our interest in the salvation, how can we expect the joy of it? But, when we truly repent, we may pray and hope that God will restore to us those joys. Those that sow in penitential tears shall reap in the joys of God's salvation when the times of refreshing shall come. (2.) It had made him weak, and therefore he prays, "Uphold me with the free Spirit: I am ready to fall, either into sin or into despair; Lord, sustain me; my own spirit" (though the spirit of a man will go far towards the sustaining of his infirmity) "is not sufficient; if I be left to myself, I shall certainly sink; therefore uphold me with thy Spirit, let him counterwork the evil spirit that would cast me down from my excellency. Thy Spirit is a free spirit, a free gent himself, working freely" (and that makes those free whom he works upon, for where the Spirit of the Lord is there is liberty) - "thy ingenuous princely Spirit." He was conscious to himself of having acted, in the matter of Uriah, very disingenuously and unlike a prince; his behaviour was base and paltry: "Lord," says he, "let thy Spirit inspire my soul with noble and generous principles, that I may always act as becomes me." A free spirit will be a firm and fixed spirit, and will uphold us. The more cheerful we are in our duty the more constant we shall be to it.
II. See what David here promises, Psa 51:13. Observe,
1.What good work he promises to do: I will teach transgressors thy ways. David had been himself a transgressor, and therefore could speak experimentally to transgressors, and resolves, having himself found mercy with God in the way of repentance, to teach others God's ways, that is, (1.) Our way to God by repentance; he would teach others that had sinned to take the same course that he had taken, to humble themselves, to confess their sins, and seek God's face; and, (2.) God's way towards us in pardoning mercy; how ready he is to receive those that return to him. He taught the former by his own example, for the direction of sinners in repenting; he taught the latter by his own experience, for their encouragement. By this psalm he is, and will be to the world's end, teaching transgressors, telling them what God had done for his soul. Note, Penitents should be preachers. Solomon was so, and blessed Paul.
2.What good effect he promises himself from his doing this: "Sinners shall be converted unto thee, and shall neither persist in their wanderings from thee, nor despair of finding mercy in their returns to thee." The great thing to be aimed at in teaching transgressors is their conversion to God; that is a happy point gained, and happy are those that are instrumental to contribute towards it, Jam 5:20.
People are in error who think that the priests of the Lord, after a lapse, although they may have exhibited true repentance, are not capable of ministering to the Lord and engaging their honorable offices, even though they may lead a good life thereafter and perform their priesthood correctly. Individuals who hold this opinion are not only in error but also seem to argue and act in opposition to the power of the keys committed to the church, of which it is said, “Whatever you shall loose on earth shall be loosed in heaven.” In short, this opinion either is not the Lord’s or it is true. Be that as it may, we believe without hesitation that both the priests of the Lord and other believers may return to their place of honor after a proper satisfaction for their error, as the Lord testifies through his prophet: “Shall he who falls not also rise again? and shall he who turns away not return?” In another passage the Lord says, “I desire not the death of the sinner, but that he may turn and live.” The prophet David, on his repentance, said, “Restore to me the joy of your salvation, and uphold me with your free Spirit.” And he indeed, after his repentance, taught others also and offered sacrifice to God, giving thereby an example to the teachers of the holy church, that if they have fallen and thereafter have exhibited a right repentance to God, they may do both things in like manner. For he taught when he said, “I will teach transgressors your ways, and sinners will be converted to you.” And he offered sacrifice for himself when he said, “The sacrifice for God is a broken spirit.” For the prophet, seeing his own transgressions purged by repentance, had no doubt as to healing those of others by preaching and by making offering to God. Thus the shedding of tears moves the mind’s feeling (passionem). And when the satisfaction is made good, the mind is turned aside from anger. For how does that person think that mercy will be shown to himself, who does not forgive his neighbor? If offences abound, then, let mercy also abound; for with the Lord there is mercy, and with him is plentiful redemption.
This is the Spirit that at the beginning "moved upon the thee of the waters; " by whom the world moves; by whom creation consists, and all things have life; who also wrought mightily in the prophets, and descended in flight upon Christ. This is the Spirit that was given to the apostles in the form of fiery tongues. This is the Spirit that David sought when he said, "Create in me a clean heart, O God, and renew a right spirit within me." Of this Spirit Gabriel also spoke to the Virgin, "The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee." By this Spirit Peter spake that blessed word, "Thou art the Christ, the Son of the living God." By this Spirit the rock of the Church was stablished. This is the Spirit, the Comforter, that is sent because of thee, that He may show thee to be the Son of God.
We shall now examine what kinds of ideas about the Spirit we hold in common, as well as those that we have gathered from the Scriptures or received from the unwritten tradition of the Fathers. First of all, who can listen to the Spirit’s titles and not be lifted up in his soul? Whose thoughts would not be raised to contemplate the supreme nature? He is called the Spirit of God, the Spirit of truth who proceeds from the Father, right Spirit, willing Spirit. His first and most proper title is Holy Spirit, a name most especially appropriate to everything that is incorporeal, purely immaterial and indivisible.
In addition to what has already been said, those who cleanse the head, which is the seat of knowledge, would do well to hold fast to Christ as their head. It is from him that the entire body is joined together and reconciled. And to cast aside our sin which arises and to seek to surpass the better part. It is also good that they should cleanse the shoulder so that it will be able to bear the cross of Christ, which is not borne easily by everyone. It is also good to consecrate the hands and the feet—the hands so that they may be lifted up in every holy place and grasp the teachings of Christ lest the Lord be angered at any time and to believe the Word by living it as when it was given into the hand of the prophet; the feet so that they will not be quick to shed blood or rush into evil but that they may be ready to hurry to the gospel and to their high calling and to receive Christ, who washes and purifies them. If anyone is clean in his stomach, which is able to hold and digest the food of the Word, he should not make a god of nourishment and meat that perishes; rather he should especially reduce its size so that he may receive the Word of the Lord in its very midst and to grieve deeply over the failing of Israel. I also find the heart and the inward parts worthy of honor. David convinced me of this when he asked that a clean heart be created within him and a right spirit be consecrated in his innermost being—by this I think he clearly means his mind and its emotions or thoughts.
It would be better to be defiled with unclean mud than with sins. A person who is defiled with mud can wash it off in a short time and become like one who had never fallen into that mire at all. But one who has fallen into the deep pit of sin has contracted a defilement that is not cleansed by water but needs a long period of time, strict repentance, tears and lamentations and more wailing—and that more fervent than we show at the loss of one of our dearest friends. For this defilement attaches to us from without, wherefore we also quickly put it away, but the other is generated from within, where it is more difficult to wash it off and to cleanse ourselves from it. “For from the heart” (it is said) “proceed evil thoughts, fornications, adulteries, thefts, false witnesses.” Thus, the prophet also said, “Create in me a clean heart, O God.” And another prophet said, “Wash your heart from wickedness, O Jerusalem.” (You see that it is both our [work] and God’s.) And again, “Blessed are the pure in heart, for they shall see God.”
“The one who says, I know him, and does not keep his commandments is a liar, and the truth is not in him. But whoever keeps his word, in him the love of God has been truly perfected. By this we know that we are in him; he who says that he abides in him ought himself also to walk as he walked.” My reason for telling you, little children, that everyone who is born of God does not sin, is that you should not sin and that you should know that as long as you do not sin you abide in the birth that God has given you. Truly, they who abide in that birth cannot sin. “For what does light have in common with darkness? Or Christ with Belial?” As day is distinct from night, so righteousness and unrighteousness, sin and good works, Christ and Antichrist cannot blend. If we give Christ a lodging place in our hearts, we banish the devil therefrom. If we sin and the devil enters through the gate of sin, Christ will immediately withdraw. Hence David after sinning says, “Restore to me the joy of your salvation,” that is, the joy that he had lost by sinning.
But see what he annexes: "With Principal Spirit," he says, "confirm Thou me." Wherein "confirm"? Because You have pardoned me, because I am secure, that what You have forgiven is not to be ascribed, on this being made secure and with this grace confirmed, therefore I am not ungrateful. But I shall do what? "I would teach unrighteous men Your ways" [Psalm 51:13]. Being myself of the unrighteous (that is, one that was myself an unrighteous man, now no longer unrighteous; the Holy Spirit not having been taken away from me, and I being confirmed with Principal Spirit). "I would teach unrighteous men Your ways." What ways will you teach unrighteous men? "And ungodly men to You shall be converted." If David's sin is counted for ungodliness, let not ungodly men despair of themselves, forasmuch as God has spared an ungodly man; but let them take heed that to Him they be converted, that His ways they learn. But if David's deed is not counted for ungodliness, but this is properly call ungodliness, namely, to apostatize from God, not to worship one God, or never to have worshipped, or to have forsaken, Him whom one did worship, then what he says has the force of superabundance, "And ungodly men shall to You be converted." So full are you of the fatness of mercy, that for those converted to You, not only sinners of any sort, but even ungodly, there is no cause for despair. Wherefore? That believing on Him that justifies an ungodly man, their faith may be counted for righteousness. [Romans 4:5]
So then Rome, the head of the nations, has these two lights of the nations lit by the one who enlightens every person who comes into this world47—one light in which God has exalted the most abject lowliness, the other in which he cured the wickedness that deserved to be condemned. With the former let us learn not to be proud, with the latter not to despair. How simply these great examples have been set before us, and how salutary they are! Let us always commemorate them and in praising them glorify that true light. So none of us should get a swollen head about having a high position in the world; Peter was a fisherman. None of us, reflecting on our own iniquity, should run away from God's mercy; Paul was a persecutor. The former says, "The Lord has become the refuge of the poor"; the latter says, "Let me teach the wicked your ways, and the godless will be converted to you."
As for the fact that he says, “And he has looked upon,” he indicates the grace of the one who shows mercy. We say that they see that we look upon those to whom we declare that something has also been offered. And consider that he did not say that the sins were seen, but rather the sons of men were. For when God looks at their sins, he punishes them; when he looks at a person, he absolves them, just as he will say in Psalm 51, “Turn your face from my sins,” and elsewhere, “Do not turn your face away from me.” Thus, we must understand and retain this salutary distinction.
It is only by participation in the divine goodness that a rational creature is recognized as being capable of becoming good. Hence the Lord also bears witness by a benevolent promise that “your Father from heaven will give his good Spirit to those who ask him.” This is to point out that those who of themselves are evil can become good through receiving the gift of the Spirit. He pledged that his good Spirit would be given by the Father to those asking for him, because whether we desire to secure faith, hope and charity, or any other heavenly goods at all, they are not bestowed on us in any other way than by the gift of the Holy Spirit. So it is that the same Spirit, in Isaiah, is named the Spirit of wisdom and understanding, the Spirit of counsel and fortitude, the Spirit of knowledge and piety, the Spirit of the fear of the Lord; and in another place, the Spirit of love and peace [and] the Spirit of grace and prayers. Undoubtedly whatever good we truly have, whatever we do well, this we receive from the lavishness of the same Spirit. When a prophet who understood this was seeking purity of heart, saying, “Create a pure heart in me, O Lord,” he immediately added, “Renew a steadfast spirit within me.” If the steadfast Spirit of the Lord does not fill our innermost being, we have no pure heart where he may abide. When in his eager longing for an advance in good for his work he had said, “Lord, I have had recourse to you, teach me to do your will,” he at once showed in what way he had to secure this when he went on, “Let your good Spirit lead me into the right way.”
Let us call to mind that he promised that [Jesus] would send the grace of the Spirit to his disciples, and he did send it. And let us take care with all watchfulness, lest by our seductive thoughts we grieve the Holy Spirit of God, in whom we have been sealed for the day of redemption. For so it is written, “The Holy Spirit will flee the pretense of discipline, and will remove himself from thoughts that are without understanding.” When the psalmist was burning with the desire to receive this Spirit, he providently sought first [to have] the guest chamber of a clean heart in which he could receive him, and so at length [he] sought the entry of so great a guest. “Create a clean heart in me, O God,” he said, “renew an upright spirit in my inmost parts.” He entreated that first a clean heart be created in him and then that an upright spirit be renewed in his inmost parts, because he knew that an upright spirit could have no place in a defiled heart.

SUMMARY
Psalms 51:13 articulates a profound commitment from a heart transformed by divine forgiveness: the repentant individual, having experienced God's restorative grace, vows to actively share God's truth with others, anticipating their spiritual conversion. This verse, arising from David's deep contrition over his grievous sin, powerfully illustrates that genuine repentance naturally overflows into a desire for others to encounter the same redemptive power and be reconciled to God, demonstrating that God's mercy not only cleanses but also commissions.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
Psalms 51:13 employs several effective literary devices to convey its profound message. Most prominently, it utilizes Parallelism, specifically a form of Synonymous Parallelism, where the two clauses express similar ideas using different but related terms. "Transgressors" parallels "sinners," and "teach thy ways" parallels "converted unto thee," reinforcing the core message of instruction leading to spiritual transformation. This structural repetition emphasizes the comprehensive nature of the desired outcome—not just knowledge, but a complete reorientation of life. Furthermore, the verse demonstrates a clear Cause and Effect relationship: David's personal experience of repentance and forgiveness (the implied cause from the preceding verses, particularly the restoration he seeks) leads directly to his resolve to teach, which in turn leads to the conversion of others (the ultimate effect). This highlights the missional imperative that flows organically from genuine spiritual renewal. There is also an element of Metonymy in "thy ways," where "ways" stands for the entire body of God's truth, character, moral law, and redemptive plan.
THEOLOGICAL AND THEMATIC CONNECTIONS
Psalms 51:13 stands as a powerful testament to the missional heart of God, demonstrating that divine forgiveness is not merely for personal comfort or private solace but for empowering believers to participate actively in God's ongoing redemptive work in the world. David's profound vow illustrates that true repentance, far from leading to isolation or shame, propels the forgiven individual into a ministry of reconciliation. It underscores the biblical principle that those who have received abundant mercy are uniquely positioned to extend it, sharing the path of God's "ways" with those still lost in "transgression" and "sin." This verse profoundly foreshadows the New Covenant reality where all believers, having been reconciled to God through Christ, become His ambassadors, pleading with others to be reconciled to Him (2 Corinthians 5:18-20). It affirms that God sovereignly uses human instruments, transformed by His grace, to bring about the spiritual turning of hearts towards Himself, manifesting His restorative power through the testimony of the redeemed.
REFLECTION AND APPLICATION
Psalms 51:13 offers a profound blueprint for the life of a truly repentant and restored believer, challenging us to consider the outward implications of our inward transformation. It dismantles the misconception that past failures disqualify us from future service; rather, our very experiences of profound sin and God's boundless grace become the most potent tools for witness and ministry. David, having fallen spectacularly and publicly, did not retreat into a life of quiet shame but emerged with a burning desire to guide others to the very source of forgiveness and restoration he had found. This verse calls us to move beyond a self-focused understanding of salvation and to embrace our God-given role as conduits of His truth and grace. Our personal testimonies of transformation are not just stories for ourselves but powerful narratives that can illuminate "God's ways" for "transgressors" and lead "sinners" to "be converted." It reminds us that the ultimate goal of our spiritual journey is not just personal holiness but active participation in God's ongoing mission to reconcile the world to Himself, leveraging our own redemption as a beacon for others.
Questions for Reflection
FAQ
Does Psalms 51:13 suggest that David, a sinner, is qualified to teach others about God's ways?
Answer: Absolutely. This verse powerfully suggests that it is precisely because David has experienced profound sin and even more profound forgiveness that he is uniquely qualified to teach. His personal journey from rebellion to repentance, and his direct, agonizing encounter with God's mercy, provide an authentic and empathetic foundation for his teaching. He teaches not from a position of sinless perfection, but from the transformative power of God's grace. This aligns with the biblical principle that those who have been forgiven much love much (Luke 7:47) and are therefore compelled to share that transformative grace. His teaching would be a living testimony to the very "ways" of God he proclaims—ways of justice, mercy, and restoration that he himself has experienced.
CHRIST-CENTERED FULFILLMENT
Psalms 51:13 finds its ultimate and most profound fulfillment in the person and mission of Jesus Christ. David's repentant vow to "teach transgressors thy ways" and see "sinners converted unto thee" prefigures the very essence of the Messiah's earthly ministry. Jesus Himself is the perfect embodiment and revelation of "God's ways"—He is not merely one path among many, but "the way, the truth, and the life" (John 14:6). He came specifically not to call the righteous, but "sinners to repentance" (Mark 2:17), demonstrating God's boundless mercy and His desire for all to turn to Him. Through His sinless life, sacrificial death on the cross, and glorious resurrection, Jesus perfectly revealed God's character and provided the ultimate, once-for-all means for the conversion of sinners, becoming the "Lamb of God, who takes away the sin of the world!" (John 1:29). The "conversion" David longed for is fully realized in the new birth brought about by the Holy Spirit through faith in Christ (John 3:3-8). Furthermore, Jesus, having perfectly fulfilled this mission, commissioned His followers—those who have experienced His forgiveness and new life—to continue this very mandate: to "go and make disciples of all nations, teaching them to observe all that I have commanded you" (Matthew 28:19-20). Thus, David's repentant promise becomes the Church's enduring mandate, empowered by the Christ who perfectly fulfilled the call to teach God's ways and convert sinners unto Himself.
