Psalm 51:2-5

2Wash away all my iniquity and cleanse me from my sin.

3For I know my transgressions, and my sin is always before me.

4Against you, you only, have I sinned and done what is evil in your sight; so you are right in your verdict and justified when you judge.

5Surely I was sinful at birth, sinful from the time my mother conceived me.
