God, be merciful to me;
On Thy grace I rest my plea;
In Thy vast, abounding grace,
My transgressions all erase.
Wash me wholly from my sin;
Cleanse from every ill within.

For my sins before me rise,
Ever present to my eyes.
I have sinned ‘gainst Thee alone.
In Thy sight this evil done;
That Thy judgment may be clear,
And Thy sentence just appear.

Lo, brought forth was I in sin;
When conceived I was unclean.
Lo, Thou dost desire to find
Truth sincere within the mind:
And Thou wilt within my heart
Wisdom unto me impart.

Then with hyssop sprinkle me,
And form sin I clean shall be.
Wash me from its stain, and lo,
I shall whiter be than snow.
Make me hear joy’s cheering voice;
Make my broken bones rejoice.

From my sins hide Thou Thy face;
My iniquities erase.
O my God, renew my heart,
And a spirit right impart.
Cast me not away from Thee,
Nor Thy Spirit take form me.

Give salvation’s’ joy again,
And a willing mind sustain.
Then thy perfect ways I’ll show
That transgressors may them know;
They converted then shall be
Sinners shall be turned to Thee. Amen. (Psalm 51)
