Isaiah 1:16-19 (KJV)
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, relieve the oppressed,
judge the fatherless, plead for the widow.
18 Come now, and let us reason together, saith the Lord:
though your sins be as scarlet, they shall be as white as snow;
though they be red like crimson, they shall be as wool.
19 If ye be willing and obedient, ye shall eat the good of the land:
