511 Have mercy on me, OÂ God, because of your unfailing love. Because of your great compassion, blot out the stain of my sins. 2 Wash me clean from my guilt. Purify me from my sin. 3 For I recognize my rebellion; it haunts me day and night. 4 Against you, and you alone, have I sinned; I have done what is evil in your sight. You will be proved right in what you say, and your judgment against me is just. 5 For I was born a sinner- yes, from the moment my mother conceived me. 6 But you desire honesty from the womb, teaching me wisdom even there.
7 Purify me from my sins, and I will be clean; wash me, and I will be whiter than snow. 8 Oh, give me back my joy again; you have broken me- now let me rejoice. 9 Don't keep looking at my sins. Remove the stain of my guilt. 10 Create in me a clean heart, OÂ God. Renew a loyal spirit within me. 11 Do not banish me from your presence, and don't take your Holy Spirit from me. 12 Restore to me the joy of your salvation, and make me willing to obey you. 13 Then I will teach your ways to rebels, and they will return to you.
14 Forgive me for shedding blood, OÂ God who saves; then I will joyfully sing of your forgiveness. 15 Unseal my lips, OÂ Lord, that my mouth may praise you.

Commentary on Psalm 51:1-6
(Read Psalm 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.
Commentary on Psalm 51:7-15
(Read Psalm 51:7-15)
Purge me with hyssop, with the blood of Christ applied to my soul by a lively faith, as the water of purification was sprinkled with a bunch of hyssop. The blood of Christ is called the blood of sprinkling, Galatians 5:1. It is the Spirit of adoption spoken to the heart. Those to whom God is the God of salvation, he will deliver from guilt; for the salvation he is the God of, is salvation from sin. We may therefore plead with him, Lord, thou art the God of my salvation, therefore deliver me from the dominion of sin. And when the lips are opened, what should they speak but the praises of God for his forgiving mercy?
