For the director of music. A psalm of David. When the prophet Nathan came to him after David had committed adultery with Bathsheba.

1 aHave mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions.
2 Wash away all my iniquity and cleanse me from my sin.
3 For I know my transgressions, and my sin is always before me.
4 Against you, you only, have I sinned and done what is evil in your sight; so you are right in your verdict and justified when you judge.
5 Surely I was sinful at birth, sinful from the time my mother conceived me.
6 Yet you desired faithfulness even in the womb; you taught me wisdom in that secret place.
7 Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow.
8 Let me hear joy and gladness; let the bones you have crushed rejoice.
9 Hide your face from my sins and blot out all my iniquity.
