Isaiah 1:16-21

Wash and make yourselves clean. Take your evil deeds out of my sight; stop doing wrong. Learn to do right; seek justice. Defend the oppressed. Take up the cause of the fatherless; plead the case of the widow. “Come now, let us settle the matter,” 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 good things of the land; but if you resist and rebel, you will be devoured by the sword.” For the mouth of the LORD has spoken. See how the faithful city has become a prostitute! She once was full of justice; righteousness used to dwell in her— but now murderers!
