response reading 27. Psalm 51. Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions. Wash away all my iniquity and cleanse me from my sin. For I know my transgressions, and my sin is always before me. Against you, you only, have I sinned and done what is evil in your sight, so that you are proved right when you speak and justified when you judge. Surely I was sinful at birth, sinful from the time my mother conceived me. Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow. Create in me a pure heart, O God, and renew a steadfast spirit within me.
