Have mercy on me, O God,
because of your unfailing love.
Because of your great compassion,
blot out the stain of my sins.
Wash me clean from my guilt.
Purify me from my sin.
For I recognize my rebellion;
it haunts me day and night.
Against you, and you alone, have I sinned;
I have done what is evil in your sight.
You will be proved right in what you say,
and your judgment against me is just. Psalm 51:1-4. NLT
