Psalms 51:1-5

1Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions. 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.
