Psalm 51:1-4, 10-12

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.

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.
