Passage: Psalm 51:2-4 (ESV Bible Online)

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 you, you only, have I sinned
and done what is evil in your sight,
so that you may be justified in your words
and blameless in your judgment.
