Book of Isaiah 1:10.16-20.
Hear the word of the LORD, princes of Sodom! Listen to the instruction of our God, people of Gomorrah!
Wash yourselves clean! Put away your misdeeds from before my eyes; cease doing evil;
learn to do good. Make justice your aim: redress the wronged, hear the orphan’s plea, defend the widow.
Come now, let us set things right, says the LORD: Though your sins be like scarlet, they may become white as snow; Though they be crimson red, they may become white as wool.
If you are willing, and obey, you shall eat the good things of the land;
But if you refuse and resist, the sword shall consume you: for the mouth of the LORD has spoken!
