A Prayer for Cleansing
51 1 Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions. 2 Wash away all my iniquity and cleanse me from my sin. 3 For I know my transgressions, and my sin is always before me. 4 Against 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. 5 Surely I was sinful at birth, sinful from the time my mother conceived me. 6 Yet you desired faithfulness even in the womb; you taught me wisdom in that secret place.
51:1 In Hebrew texts 51:1-19 is numbered 51:3-21.
