Have mercy on me, God, in Your Kindness, in Your Compassion blot out my offence. O wash me more and more from my guilt and cleanse me from my sin. My offences truly I know them: my sin is always before me. Against You, You alone, have I sinned; what is evil in Your Sight I have done. A pure heart create for me, O God; put a steadfast spirit within me. Do not cast me away from Your Presence, nor deprive me of Your Holy Spirit. Give me again the joy of Your Help; with a spirit of fervour sustain me. O Lord, open my lips and my mouth shall declare Your Praise.
