Isaiah 1:18-20

18 “Come now, and let us reason together,” says 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 are 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.”
