For SATB Choir. A harmonically rich and poignant setting of Psalm 6: 2a, 3a-4 — a Psalm which doesn't show up in the Sunday lectionary, but is compatible with all of the penitential Psalm readings, so don't be afraid to try it!
Have mercy upon me, O Lord, for I am weak.
My soul is also sore troubled.
Turn thee, O Lord, and deliver my soul.
O save me, for thy mercy's sake.
FYI: The penetential Psalms are: 6, 32, 38, 51, 102, 130, 143.
