Create in me a clean heart, O God.

Have mercy on me,O God, according to your steadfast love; according to your 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 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. 5 Behold, I was brought forth in iniquity, and in sin did my mother conceive me. 6 Behold, you delight in truth in the inward being, and you teach me wisdom in the secret heart. 7 Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow.
