Isaiah 1: 10, 16 - 20
10 Hear the word of the LORD, you rulers of Sodom! Give ear to the teaching of our God, you people of Gomor'rah!
16 Wash yourselves; make yourselves clean; remove the evil of your doings from before my eyes; cease to do evil,
17 learn to do good; seek justice, correct oppression; defend the fatherless, plead for the widow.
18 "Come now, let us reason together, says the LORD: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool.
19 If you are willing and obedient, you shall eat the good of the land;
20 But if you refuse and rebel, you shall be devoured by the sword; for the mouth of the LORD has spoken."
