Commentary on Psalms 40 verses 6–10
6 ¶ Sacrifice and offering thou didst not desire; mine ears hast thou opened: burnt offering and sin offering hast thou not required.
7 Then said I, Lo, I come: in the volume of the book it is written of me,
8 I delight to do thy will, O my God: yea, thy law is within my heart.
9 I have preached righteousness in the great congregation: lo, I have not refrained my lips, O LORD, thou knowest.
10 I have not hid thy righteousness within my heart; I have declared thy faithfulness and thy salvation: I have not concealed thy lovingkindness and thy truth from the great congregation.
The psalmist, being struck with amazement at the wonderful works that God had done for his people, is strangely carried out here to foretel that work of wonder which excels all the rest and is the foundation and fountain of all, that of our redemption by our Lord Jesus Christ. God's thoughts, which were to us-ward concerning that work, were the most curious, the most copious, the most gracious, and therefore to be most admired. This paragraph is quoted by the apostle (Heb 10:5, etc.) and applied to Christ and his undertaking for us. As in the institutions, so in the devotions, of the Old Testament saints were aware of; and, when the apostle would show us the Redeemer's voluntary undertaking of his work, he does not fetch his account out of the book of God's secret counsels, which belong not to us, but from the things revealed. Observe,
I. The utter insufficiency of the legal sacrifices to atone for sin in order to our peace with God and our happiness in him: Sacrifice and offering thou didst not desire; thou wouldst not have the Redeemer to offer them. Something he must have to offer, but not these (Heb 8:3); therefore he must not be of the house of Aaron, Heb 7:14. Or, In the days of the Messiah burnt-offering and sin-offering will be no longer required, but all those ceremonial institutions will be abolished. But that is not all: even while the law concerning them was in full force it might be said, God did not desire them, nor accept them, for their own sake. They could not take away the guilt of sin by satisfying God's justice. The life of a sheep, which is so much inferior in value to that of a man (Mat 12:12), could not pretend to be an equivalent, much less an expedient to preserve the honour of God's government and laws and repair the injury done to that honour by the sin of man. They could not take away the terror of sin by pacifying the conscience, nor the power of sin by sanctifying the nature; it was impossible, Heb 9:9; Heb 10:1-4. What there was in them that was valuable resulted from their reference to Jesus Christ, of whom they were types - shadows indeed, but shadows of good things to come, and trials of the faith and obedience of God's people, of their obedience of God's people, of their obedience to the law and their faith in the gospel. But the substance must come, which is Christ, who must bring that glory to God and that grace to man which it was impossible those sacrifices should ever do.
II. The designation of our Lord Jesus to the work and office of Mediator: My ears hast thou opened. God the Father disposed him to the undertaking (Isa 50:5, Isa 50:6) and then obliged him to go through with it. My ear hast thou digged. It is supposed to allude to the law and custom of binding servants to serve for ever by boring their ear to the doorpost; see Exo 21:6. Our Lord Jesus was so in love with his undertaking that he would not go out free from it, and therefore engaged to persevere for ever in it; and for this reason he is able to save us to the uttermost, because he has engaged to serve his Father to the uttermost, who upholds him in it, Isa 42:1.
III. His own voluntary consent to this undertaking: "Then said I, Lo, I come; then, when sacrifice and offering would not do, rather than the work should be undone; I said, Lo, I come, to enter the lists with the powers of darkness, and to advance the interests of God's glory and kingdom." This intimates three things: - 1. That he freely offered himself to this service, to which he was under no obligation at all prior to his own voluntary engagement. It was no sooner proposed to him than, with the greatest cheerfulness, he consented to it, and was wonderfully well pleased with the undertaking. Had he not been perfectly voluntary in it, he could not have been a surety, he could not have been a sacrifice; for it is by this will (this animus offerentis - mind of the offerer) that we are sanctified, Heb 10:10. 2. That he firmly obliged himself to it: "I come; I promise to come in the fulness of time." And therefore the apostle says, "It was when he came into the world that he had an actual regard to this promise, by which he had engaged his heart to approach unto God." He thus entered into bonds, not only to show the greatness of his love, but because he was to have the honour of his undertaking before he had fully performed it. Though the price was not paid, it was secured to be paid, so that he was the Lamb slain from the foundation of the world. 3. That he frankly owned himself engaged: He said, Lo, I come, said it all along to the Old Testament saints, who therefore knew him by the title of ho erchomenos - He that should come. This word was the foundation on which they built their faith and hope, and which they looked and longed for the accomplishment of.
IV. The reason why he came, in pursuance of his undertaking - because in the volume of the book it was written of him, 1. In the close rolls of the divine decree and counsel; there it was written that his ear was opened, and he said, Lo, I come; there the covenant of redemption was recorded, the counsel of redemption was recorded, the counsel of peace between the Father and the Son; and to that he had an eye in all he did, the commandment he received of his Father. 2. In the letters patent of the Old Testament. Moses and all the prophets testified of him; in all the volumes of that book something or other was written of him, which he had an eye to, that all might be accomplished, Joh 19:28.
V. The pleasure he took in his undertaking. Having freely offered himself to it, he did not fail, nor was discouraged, but proceeded with all possible satisfaction to himself (Psa 40:8. 9): I delight to do thy will, O my God! It was to Christ his meat and drink to go on with the work appointed to him (Joh 4:34); and the reason here given is, Thy law is within my heart; it is written there, it rules there. It is meant of the law concerning the work and office of the Mediator, what he was to do and suffer; this law was dear to him and had an influence upon him in his whole undertaking. Note, When the law of God is written in our hearts our duty will be our delight.
VI. The publication of the gospel to the children of men, even in the great congregation, Psa 40:9, Psa 40:10. The same that as a priest wrought out redemption for us, as a prophet, by his own preaching first, then by his apostles, and still by his word and Spirit, makes it know to us. The great salvation began to be spoken by the Lord, Heb 2:3. It is the gospel of Christ that is preached to all nations. Observe, 1. What it is that is preached: It is righteousness (Psa 40:9), God's righteousness (Psa 40:10), the everlasting righteousness which Christ has brought in (Dan 9:24); compare Rom 1:16, Rom 1:17. It is God's faithfulness to his promise, and the salvation which had long been looked for. It is God's lovingkindness and his truth, his mercy according to his word. Note, In the work of our redemption we ought to take notice how brightly all the divine attributions shine, and give to God the praise of each of them. 2. To whom it is preached - to the great congregation, Psa 40:9 and again Psa 40:10. When Christ was here on earth he preached to multitudes, thousands at a time. The gospel was preached both to Jews and Gentiles, to great congregations of both. Solemn religious assemblies are a divine institution, and in them the glory of God, in the face of Christ, ought to be both praised to the glory of God and preached for the edification of men. 3. How it is preached - freely and openly: I have not refrained my lips; I have not hid it; I have not concealed it. This intimates that whoever undertook to preach the gospel of Christ would be in great temptation to hide it and conceal it, because it must be preached with great contention and in the face of great opposition; but Christ himself, and those whom he called to that work, set their faces as a flint (Isa 50:7) and were wonderfully carried on in it. It is well for us that they were so, for by this means our eyes come to see this joyful light and our ears to hear this joyful sound, which otherwise we might for ever have perished in ignorance of.

Hebrews 10:1-14AD 69
For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect. For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins. But in those sacrifices there is a remembrance again made of sins every year. For it is not possible that the blood of bulls and of goats should take away sins. Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: In burnt offerings and sacrifices for sin thou hast had no pleasure. Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God. Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second. [Psalms 40:6-8] By the which will we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; From henceforth expecting till his enemies be made his footstool. For by one offering he hath perfected for ever them that are sanctified.
Ambrose of MilanAD 397
Commentaries on the Twelve Davidic Psalms
Because there is one will, there is one substance, there is inseparable majesty and the power of the Trinity. But there is another voice, that of the flesh; and yet, it too consents to God’s will.… Christ accepted death and crucifixion so as to crucify the flesh. For my sake he took on himself the combat, so that he might conquer me. Though Christ’s flesh was strong and not liable to sin, he nevertheless took on my sins. He took on my weaknesses and infirmities, though he himself was without infirmity.… He who is all pure took on our flesh to make it all pure. He, the immortal one, took on our flesh to make us immortal.
JeromeAD 420
HOMILY ON PSALM 108[109]
Let the Jews perceive that they have not prevailed against me, but that it is your will that I suffer. Besides, I desired to suffer; that is why I say in my human nature: “To do your will, O my God, is my delight.” It was your will and mine that I suffer; not their plottings and power did it, but you and I desired it. You, in truth, struck your Shepherd, and the sheep have been scattered.… That I suffer was your will and mine also. What you desired, I also desired.
Augustine of HippoAD 430
Exposition on Psalm 40
"In the head of the Book it is written of me, that I should fulfil Your will: O my God, I am willing, and Your Law is within my heart" [Psalm 40:8]. Behold! He turns His regards to His members. Behold! He has Himself "fulfilled the will" of the Father. But in what "beginning of a Book" is it written of Him? Perhaps in the beginning of this Book of Psalms. For why should we seek far for it, or examine into other books for it? Behold! It is written in the beginning of this Book of Psalms! "His will is in the Law of the Lord;" that is, "'O my God, I am willing,' and 'Your Law is within my heart;'" that is the same as, "And in His Law does he meditate day and night."

SUMMARY
Psalms 40:8 profoundly articulates the psalmist's deep, joyful, and volitional commitment to God's will, stemming from an internal transformation rather than mere external obligation. This verse serves as a powerful testament to heartfelt obedience, where divine instruction is not just intellectually assented to but is profoundly internalized, actively shaping one's deepest desires, motivations, and moral character. It beautifully encapsulates the essence of true devotion: a willing and delighted alignment of one's entire being with the divine purpose, finding ultimate satisfaction and flourishing in living according to God's perfect design.
CONTEXT
Literary Context: Psalms 40 is a composite psalm, often attributed to David, seamlessly blending elements of thanksgiving, lament, and commitment. It commences with the psalmist's vivid recounting of God's miraculous deliverance from a "horrible pit" and "miry clay" (Psalms 40:1-3). This profound act of salvation elicits not only gratitude but also a renewed and public declaration of devotion. Verses 6-8 mark a pivotal transition from God's saving acts to the psalmist's personal response, emphasizing that God desires not mere ritualistic sacrifices but a surrendered heart and a willing ear. This sets the stage for the deeply personal declaration in verse 8, which then provides the foundational commitment for the subsequent prayers for continued deliverance and justice against adversaries in the latter half of the psalm (Psalms 40:11-17). The psalmist's delight in God's will undergirds his confidence in God's ongoing faithfulness.
Historical & Cultural Context: The historical backdrop of Psalms 40, likely during the Israelite monarchy, places it firmly within the covenantal framework established at Sinai, where the Torah (God's law) was central to Israel's identity and their relationship with Yahweh. While the Mosaic Law provided external statutes and sacrificial requirements, a recurring theme throughout Israel's prophetic tradition was the inadequacy of mere outward observance without genuine inward transformation. Prophets like Samuel (1 Samuel 15:22) and Isaiah (Isaiah 1:11-17) consistently emphasized that God desired a sincere heart over ritualistic adherence. The concept of God's law being "within the heart" in Psalms 40:8 is a profound anticipation of the New Covenant promises found in prophetic texts like Jeremiah 31:33 and Ezekiel 36:26-27, where God would supernaturally write His law on the hearts of His people, moving beyond external compliance to an internalized desire for righteousness. This verse thus bridges the Old Covenant's emphasis on revealed law with a deeper, more personal understanding of devotion that foreshadows future spiritual realities.
Key Themes: Psalms 40:8 powerfully contributes to several overarching themes within the Psalter and the broader biblical narrative. Firstly, it highlights wholehearted obedience and delight, asserting that true submission to God's commands is not a burdensome obligation but a profound source of genuine pleasure and satisfaction. This challenges a legalistic understanding of faith, promoting a joyful and willing alignment with divine purpose. Secondly, the verse underscores the theme of internalized law and spiritual transformation, moving beyond a superficial adherence to God's statutes to an inner conviction where His principles are deeply rooted in one's very being. This directly anticipates the New Covenant promise of a transformed heart, where God's law is written not on tablets of stone but on human hearts, leading to an organic desire to follow Him. Thirdly, the intimate address "O my God" reinforces the theme of a personal and intimate relationship with the Divine. This profound obedience flows from a deep, loving relationship with God, characterized by trust and personal knowledge, rather than from fear or impersonal obligation, reflecting the covenantal intimacy prevalent throughout the Psalms, such as in Psalms 23:1.
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
Psalms 40:8 masterfully employs several significant literary devices that amplify its meaning and emotional resonance. The most prominent is Metaphor, powerfully illustrated in the phrase "thy law is within my heart." This is not a literal placement of written text within a physical organ but a profound image conveying the complete internalization and integration of God's divine instruction into the very core of one's being. It suggests that God's truth has become an intrinsic part of the psalmist's identity, influencing his thoughts, desires, and actions from the deepest level. The use of Personal Address ("O my God") creates an intimate and direct tone, emphasizing the psalmist's personal, covenantal relationship with the Divine and the deeply relational nature of his commitment. Furthermore, the verse exhibits Synonymous Parallelism in its structure, where the second clause ("yea, thy law [is] within my heart") reinforces and explains the first ("I delight to do thy will, O my God"). This creates a sense of unity and logical progression, demonstrating that the inner state of having God's law inscribed on the heart directly leads to the outward expression of delightful obedience.
THEOLOGICAL AND THEMATIC CONNECTIONS
Psalms 40:8 articulates a profound theological truth: genuine obedience to God is not merely external compliance with rules but springs from an inner delight and a deep, internalized understanding of His will. This concept resonates deeply with the biblical emphasis on the heart as the wellspring of life and the locus of true faith, where transformation begins. It transcends a purely legalistic framework, moving towards a relational one, where God's commands are embraced out of love and a fervent desire to please Him, rather than out of fear of punishment or hope of reward. This verse powerfully foreshadows the New Covenant promise of a transformed heart, where God's Spirit enables believers to genuinely desire and live out His will, making His law an intrinsic part of their renewed nature. It underscores that God seeks not just our actions, but our affections, our will, and our very selves, fully surrendered to His loving and perfect guidance.
REFLECTION AND APPLICATION
Psalms 40:8 stands as both a profound aspiration and a challenging invitation for believers today. It calls us to cultivate a spiritual posture where obedience to God's will is not a reluctant duty or a burdensome obligation, but a genuine and profound delight. This requires a fundamental shift in perspective, viewing God's commands not as restrictive limitations but as liberating pathways to true flourishing, joy, and eternal purpose. It compels us to honestly examine the condition of our hearts: Is God's law merely an external rulebook we grudgingly consult, or has it been internalized, shaping our deepest desires, motivations, and the very fabric of our character? True spiritual maturity involves a growing, Spirit-enabled alignment of our will with God's, where His principles become intrinsically woven into our renewed nature. This verse encourages us to actively seek God's will in every area of our lives, trusting that His ways are always best, and finding our greatest satisfaction and freedom in living for His glory and according to His perfect design.
Questions for Reflection
FAQ
What is the significance of the phrase "thy law is within my heart"?
Answer: The phrase "thy law is within my heart" signifies a profound and transformative internalization of God's divine instruction and will. In Hebrew thought, the "heart" (Heb. mêʻeh or lēḇ) refers to the entire inner person—the seat of intellect, emotions, will, conscience, and moral character. Therefore, it means that God's commands and teachings are not merely external rules to be followed out of duty, but have become deeply rooted convictions, shaping one's desires, motivations, and actions from the very core of one's being. It implies a willing, joyful, and organic acceptance of God's ways, where obedience flows naturally from an inner transformation rather than from external compulsion or fear. This concept powerfully anticipates the New Covenant promise, where God's law would be written on the hearts of His people, enabling a genuine and Spirit-empowered obedience (as seen in Jeremiah 31:33 and Ezekiel 36:26-27).
CHRIST-CENTERED FULFILLMENT
Psalms 40:8 finds its ultimate and perfect fulfillment in the person and redemptive work of Jesus Christ. The New Testament, particularly in Hebrews 10:5-7, directly quotes Psalms 40:6-8 and applies it to Christ's incarnation and mission. The author of Hebrews reveals that Christ, in coming into the world, declared, "Sacrifice and offering you have not desired, but a body have you prepared for me; in burnt offerings and sin offerings you have taken no pleasure. Then I said, ‘Behold, I have come to do your will, O God, as it is written of me in the scroll of the book.'" This passage demonstrates that Jesus perfectly embodied the psalmist's declaration: His entire earthly life was a living testament to delighting in and flawlessly fulfilling the Father's will. Unlike fallen humanity, whose hearts are often rebellious and prone to wander, Christ's heart was always perfectly aligned with God's law, not merely as an external code, but as His intrinsic, divine desire. From His willing submission to baptism "to fulfill all righteousness" (Matthew 3:15) to His agonizing prayer in Gethsemane, "not my will, but yours be done" (Luke 22:42), Jesus consistently demonstrated a joyful, unwavering, and perfect commitment to His Father's will, culminating in His obedient sacrifice on the cross (Philippians 2:8). He is the Lamb of God who perfectly fulfilled the Law, not by external conformity, but by an internal, divine delight, thereby making a way for all who believe in Him to have God's law written on their own hearts through the indwelling Holy Spirit, enabling them to also find delight in doing God's will.
