"The Lord was extremely angry with your ancestors.
So tell the people: This is what the Lord of Hosts says: Return to Me"-[this is] the declaration of the Lord of Hosts-"and I will return to you, says the Lord of Hosts.
Do not be like your ancestors; the earlier prophets proclaimed to them: This is what the Lord of Hosts says: Turn from your evil ways and your evil deeds. But they did not listen or pay attention to Me"-the Lord's declaration.
