Psalm 51:6-10

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.
