Isaiah 1:16-18

Darby(i) 16 Wash you, make you clean; put away the evil of your doings from before mine eyes; -- cease to do evil, 17 learn to do well: seek judgment, gladden the oppressed, do justice to the fatherless, plead for the widow. 18 Come now, let us reason together, saith Jehovah: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
