Psalm 50 : 3-4, 12-13, 18-19
Have mercy on me, o God, in Your love. In Your great compassion blot out my sin. Wash me thoroughly of my guilt; cleanse me of evil.
Create in me, o God, a pure heart; give me a new and steadfast spirit. Do not cast me out of Your presence nor take Your Holy Spirit from me.
You take no pleasure in sacrifice; were I to give a burnt offering, You would not delight in it. O God, my sacrifice is a broken spirit; a contrite heart You will not despise.
