Psalm 50 (51)

Have mercy on me, O God, according to Your great mercy, and according to the abundance of Your kindness cleanse my iniquity.
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 alone I have sinned, and before You I have done evil,
Yet You are righteous in Your words and will judge rightly.
For I was conceived in iniquity, and my mother bore me in sin.
For You have loved truth, revealing to me the hidden and secret wisdom of Yourself.
Sprinkle me with hyssop, and I shall be cleansed; wash me, and I shall be whiter than snow.
Grant me to hear joy and gladness; the broken bones shall rejoice.
Turn away Your face from my sins and cleanse all my iniquities.
Create in me a pure heart, O God, and renew a right spirit within my innermost being.
Do not cast me away from Your face, nor withdraw Your Holy Spirit from me.
Restore to me the joy of Your salvation, and establish me with a victorious spirit.
I will show the transgressors Your ways, and the ungodly will turn to You.
Deliver me from the guilt of blood, O God, O God of my salvation,
And my tongue will joyfully proclaim Your righteousness.
Lord, open my wounds, and my mouth will declare Your praise.
For if You desired sacrifices, I would give them, yet burnt offerings are not dear to You.
A sacrifice to God is a broken spirit, a contrite and humble heart; God will not despise it.
Blessed are You, Lord, with Your favor upon Zion, and let the walls of Jerusalem be moved.
Then You will accept as a sacrifice the offering of truth, the offering and burnt offering; then they will lay a calf upon Your altar.
