10 Hear what Yahweh says, you rulers of Sodom; listen to what our God teaches, you people of Gomorrah.
16 wash, make yourselves clean. Take your wrong-doing out of my sight. Cease doing evil.
17 Learn to do good, search for justice, discipline the violent, be just to the orphan, plead for the widow.
18 'Come, let us talk this over,' says Yahweh. 'Though your sins are like scarlet, they shall be white as snow; though they are red as crimson, they shall be like wool.
19 If you are willing to obey, you shall eat the good things of the earth.
20 But if you refuse and rebel, the sword shall eat you instead -- for Yahweh's mouth has spoken.'
Isaiah 1:10, 16-20
