Psalm 51:1-10 RSV

1 To the choirmaster. A Psalm of David, when Nathan the prophet came to him, after he had gone in to Bathsheba. Have mercy on me, O God, according to thy steadfast love; according to thy abundant mercy blot out my transgressions.
2 Wash me thoroughly from my iniquity, and cleanse me from my sin!
3 For I know my transgressions, and my sin is ever before me.
4 Against thee, thee only, have I sinned, and done that which is evil in thy sight, so that thou art justified in thy sentence and blameless in thy judgment.
5 Behold, I was brought forth in iniquity, and in sin did my mother conceive me.
6 Behold, thou desirest truth in the inward being; therefore teach me wisdom in my secret heart.
7 Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow.
8 Fill me with joy and gladness; let the bones which thou hast broken rejoice.
9 Hide thy face from my sins, and blot out all my iniquities.
10 Create in me a clean heart, O God, and put a new and right spirit within me.
