Psalms 51:13-18

Then I will teach your ways to rebels, and they will return to you. Forgive me for shedding blood, O God who saves; then I will joyfully sing of your forgiveness. Unseal my lips, O Lord, that my mouth may praise you. You do not desire a sacrifice, or I would offer one. You do not want a burnt offering. The sacrifice you desire is a broken spirit. You will not reject a broken and repentant heart, O God. Look with favor on Zion and help her; rebuild the walls of Jerusalem.
