“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 you are right in your verdict
    and justified when you judge.
Surely I was sinful at birth,
    sinful from the time my mother conceived me.
Yet you desired faithfulness even in the womb;
    you taught me wisdom in that secret place.
Cleanse me with hyssop, and I will be clean;
    wash me, and I will be whiter than snow.
Let me hear joy and gladness;
    let the bones you have crushed rejoice.
Hide your face from my sins
    and blot out all my iniquity.
Create in me a pure heart, O God,
    and renew a steadfast spirit within me.
Do not cast me from your presence
    or take your Holy Spirit from me.
Restore to me the joy of your salvation
    and grant me a willing spirit, to sustain me.
Then I will teach transgressors your ways,
    so that sinners will turn back to you.”

Psalm 51
