Isaiah 1:16-20 (Eve of the Theophany)

Wash yourselves; make yourselves clean; remove the evil of your doings from before my eyes; cease to do evil, learn to do good; seek justice, correct oppression; defend the fatherless, plead for the widow. “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. If you are willing and obedient, you shall eat the good of the land; But if you refuse and rebel, you shall be devoured by the sword; for the mouth of the LORD has spoken.”
