Be gracious to me, O God, according to your lovingkindness; according to the greatness of Your compassion blot out my transgressions.
Wash me thoroughly from my iniquity and cleanse me from my sin.
For I know my transgressions, and my sin is ever before me.
Against You, You only, I have sinned and done what is evil in You sight, so that You are justified when you speak and blameless when You judge.
Behold, You desire truth in the innmost being, and in the hidden part You will make me know wisdom.
Purify me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow.
Hide Your face from my sins and blot out all my iniquities.
Create in me a clean heart, O God, and renew a steadfast spirit within me.
Do not case me away from Your presence and do not take Your Holy Spirit from me.
Restore to me the joy of Your salvation and sustain me with a willing spirit.
O Lord, open my lips, that my mouth may declare Your praise.
For You do not delight in sacrifice, otherwise I would give it; You are not pleased with burnt offering.
The sacrifices of God are a broken spirit; a broken and contrite heart, O God, You will not despise.
(Psalm 51: 1-4, 6-7, 9-12, 15-17)
