Psalms 51:1-4

1 Have mercy on me, God, according to your loving kindness.  According to the multitude of your tender mercies, blot out my transgressions.

2 Wash me thoroughly from my iniquity.  Cleanse me from my sin.

3 For I know my transgressions.  My sin is constantly before me.

4 Against you, and you only, have I sinned,  And done that which is evil in your sight;  That you may be proved right when you speak,  And justified when you judge.
