Isaiah 1:16-20

16 Wash you, make you clean; put away the evil of your doings from before my 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, said 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 you be willing and obedient, you shall eat the good of the land:

20 But if you refuse and rebel, you shall be devoured with the sword: for the mouth of the LORD has spoken it.
