Psalm 50 (51)
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.
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,
that I may teach transgressors your ways
and sinners may return to you.
