Psalm 51

PSALM 51Ps 51:1-19. On the occasion, compare 2Sa 11:12. The Psalm illustrates true repentance, in which are comprised conviction, confession, sorrow, prayer for mercy, and purposes of amendment, and it is accompanied by a lively faith.1-4. A plea for mercy is a confession of guilt.blot out—as from a register.transgressions—literally, "rebellions" (Ps 19:13; 32:1).

51:1-6 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, who alone can heal them? he drew up, by Divine teaching, an account of the workings of his heart toward God. Those that truly repent of their sins, will not be ashamed to own their repentance. Also, he instructs others what to do, and what to say. David had not only done much, but suffered much in the cause of God; yet he flees to God's infinite mercy, and depends upon that alone for pardon and peace. He begs the pardon of sin. The blood of Christ, sprinkled upon the conscience, blots out the transgression, and, having reconciled us to God, reconciles us to ourselves. The believer longs to have the whole debt of his sins blotted out, and every stain cleansed; he would be thoroughly washed from all his sins; but the hypocrite always has some secret reserve, and would have some favorite lust spared. David had such a deep sense of his sin, that he was continually thinking of it, with sorrow and shame. His sin was committed against God, whose truth we deny by wilful sin; with him we deal deceitfully. And the truly penitent will ever trace back the streams of actual sin to the fountain of original depravity. He confesses his original corruption. This is that foolishness which is bound in the heart of a child, that proneness to evil, and that backwardness to good, which is the burden of the regenerate, and the ruin of the unregenerate. He is encouraged, in his repentance, to hope that God would graciously accept him. Thou desirest truth in the inward part; to this God looks, in a returning sinner. Where there is truth, God will give wisdom. Those who sincerely endeavour to do their duty shall be taught their duty; but they will expect good only from Divine grace overcoming their corrupt nature.

"\nHave mercy upon me, O God,.... David, under a sense of sin, does not run away from God, but applies unto him, and casts himself at his feet, and upon his mercy; which shows the view he had of his miserable condition, and that he saw there was mercy in God, which gave him hope; and upon his bended knees, and in the exercise of faith, he asks for it;\n\naccording to thy lovingkindness; not according to his merits, nor according to the general mercy of God, which carnal men rely upon; but according to his everlasting and unchangeable love in Christ; from which as the source, and through whom as the medium, special mercy comes to the children of men. The acts of special mercy are according to the sovereign will of God: he is not moved to mercy neither by the merits nor misery of men, but by his free grace and favour; it is love that sets mercy to work: this is a most glaring gleam of Gospel light, which none of the inspired writers besides, except the Apostle Paul, saw, Eph 2:4;\n\naccording unto the multitude of thy tender mercies blot out my transgressions; for his sin was complicated, attended with many others; and, besides, upon a view of this, he was led to observe all his other sins; and particularly the corruption of his nature, his original sin, which he mentions, Ps 51:5. These he desires might be "blotted out"; out of the book of account, out of God's debt book; that they might not stand against him, being debts he was not able to pay or make satisfaction for; and out of the table of his own heart and conscience, where they were ever before him, and seemed to be engraven; that they might be caused to pass from him, and he might have no more conscience of them; or that they might be blotted out, as a cloud by the clear shining of the sun of righteousness, with the healing of pardoning grace in his wings; or that they might be wiped away, as any faith is wiped from any person or thing: and all this "according to the multitude of [his] tender mercies". The mercy of God is plenteous and abundant; he is rich in it, and various are the instances of it; and it is exceeding tender, like that of a father to his children, or like that of a mother to the son of her womb; and from this abundant and tender mercy springs the forgiveness of sin, Lu 1:77. The psalmist makes mention of the multitude of the mercies of God, because of the multitude of his sins, which required a multitude of mercy to forgive, and to encourage his hope of it.\n\n\n "

PSALM 51 Though David penned this psalm upon a very particular occasion, yet, it is of as general use as any of David’s psalms; it is the most eminent of the penitential psalms, and most expressive of the cares and desires of a repenting sinner. It is a pity indeed that in our devout addresses to God we should have any thing else to do than to praise God, for that is the work of heaven; but we make other work for ourselves by our own sins and follies: we must come to the throne of grace in the posture of penitents, to confess our sins and sue for the grace of God; and, if therein we would take with us words, we can nowhere find any more apposite than in this psalm, which is the record of David’s repentance for his sin in the matter of Uriah, which was the greatest blemish upon his character: all the rest of his faults were nothing to this; it is said of him (1 Ki. 15:5), That "he turned not aside from the commandment of the Lord all the days of his life, save only in the matter of Uriah the Hittite." In this psalm, I. He confesses his sin (v. 3-6). II. He prays earnestly for the pardon of his sin (v. 1, 2, 7, 9). III. For peace of conscience (v. 8, 12). IV. For grace to go and sin no more (v. 10, 11, 14). V.
