Have mercy on me,[a] 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.
