Psalm 51: 10- 17

Create a pure heart in me, O God, and put a new and loyal spirit in me.
Do not banish me from your presence; do not take your holy spirit from me.
Give me again the joy of your salvation, make me willing to obey you.
Then I will teach sinners your commands and they will turn back to you.

 Spare my life, O God, and save me
    and I will gladly proclaim your righteousness.
Help me to speak, Lord, and I will praise you.

You do not want sacrifices, or I would offer them;
you are not pleased with burnt offerings.
My sacrifice is a humble spirit, O God; you will not reject a repentant heart.
