Have mercy on me, O God, according to your unfailing love;

Psalm 51 (New International Version)

1Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions.2Wash away all my iniquity and cleanse me from my sin.3For I know my transgressions, and my sin is always before me.4Against you, you only, have I sinned and done what is evil in your sight, so that you are proved right when you speak and justified when you judge.5Surely I was sinful at birth, sinful from the time my mother conceived me.6Surely you desire truth in the inner parts; you teach me wisdom in the inmost place.7Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow.8Let me hear joy and gladness; let the bones you have crushed rejoice.9Hide your face from my sins and blot out all my iniquity.10Create in me a pure heart, O God, and renew a steadfast spirit within me.11Do not cast me from your presence or take your Holy Spirit from me.12Restore to me the joy of your salvation and grant me a willing spirit, to sustain me.13Then I will teach transgressors your ways, and sinners will turn back to you.14Save me from bloodguilt, O God, the God who saves me, and my tongue will sing of your righteousness.15O Lord, open my lips, and my mouth will declare your praise.16You do not delight in sacrifice, or I would bring it; you do not take pleasure in burnt offerings.17The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise.18In your good pleasure make Zion prosper; build up the walls of Jerusalem.19Then there will be righteous sacrifices, whole burnt offerings to delight you; then bulls will be offered on your altar.
