Psalms 51:2-10

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. 6Yet you desired faithfulness even in the womb; you taught me wisdom in that secret place. 7Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow. 8Let me hear joy and gladness; let the bones you have crushed rejoice. 9Hide your face from my sins and blot out all my iniquity. 10Create in me a pure heart, O God, and renew a steadfast spirit within me.
