Have mercy on me, O God
according to your steadfast love;
according to your abundant mercy
blot out my transgressions.
Behold, you delight in truth in the inward being,
and you teach me wisdom in the secret heart.
Purge me with hyssop, and I shall be clean;
wash me, and I shall be whiter than snow.
Let me hear joy and gladness;
let the bones that you have broken rejoice.
Hide your face from my sins,
and blot out all my iniquities.
Create in me a clean heart, O God,
and renew a right spirit within me.
Cast me not away from your presence,
and take not your Holy Spirit from me.
Restore to me the joy of your salvation,
and uphold me with a willing spirit.
The sacrifices of God are a broken spirit;
a broken and contrite heart, O God, you will not despise.
Psalm 51 (LXX Psalm 50)
