Isaiah 1:16

Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil;

Wash you, make you clean. God saith to the sinner.

Wash you ..., that he finding his inability to "make" himself "clean," may cry to God, Wash me (; ; ).

Put away the evil of your doings from before mine eyes - not mere outward reformation before man's eyes, who cannot, as God, see into the heart ().
