Psalm 51:3-7 NIV

[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. [7] Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow.
