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