Psalms 51:3-6, 12-13, 17

Have mercy on me, God, in accord with your merciful love; in your abundant compassion blot out my transgressions. Thoroughly wash away my guilt; and from my sin cleanse me. For I know my transgressions; my sin is always before me. Against you, you alone have I sinned; I have done what is evil in your eyes So that you are just in your word, and without reproach in your judgment.

A clean heart create for me, God; renew within me a steadfast spirit. Do not drive me from before your face, nor take from me your holy spirit.

Lord, you will open my lips; and my mouth will proclaim your praise.
