Isaiah 1:18-20

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 as crimson, they shall be like wool. If you are willing and obedient, you will eat the best from the land; but if you resist and rebel, you will be devoured by the sword.” For the mouth of the LORD has spoken. — Isaiah 1:18-20 (TNIV)
