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 that you are proved right when you speak and justified when you judge.
5Surely I was sinful at birth, sinful from the time my mother conceived me.
6Surely you desire truth in the inner parts ; you teach me wisdom in the inmost 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.
11Do not cast me from your presence or take your Holy Spirit from me.
12Restore to me the joy of your salvation and grant me a willing spirit, to sustain me.
13Then I will teach transgressors your ways, and sinners will turn back to you.
