Have mercy, O God, in your loving-kindness, in your compassion blot out my offenses. Thoroughly wash me from my evildoing; from my sin cleanse me. For I am mindful of my past transgressions; ever before me are my sins against you. So you speak justly when you give my sentence; right is your judgment. In me, a sinner, you seek truth long hidden; grant me your wisdom, teach my heart your secrets. From my sins purge me, purify and heal me with joy and gladness. Create a clean heart; make my spirit steadfast; take not your presence or your Spirit from me. Save and sustain me, that my tongue may tell forth your ways to sinners. Open my lips, Lord, help me sing your praises. Burnt sacrifices offer you no pleasure, but you will not scorn humble, contrite spirits; such will you welcome.
