Jeremiah 27:9

27:9 So do not listen to your prophets or to those who claim to predict the future by divination, by dreams, by consulting the dead, or by practicing magic. They keep telling you, ‘You do not need to be subject to the king of Babylon.’

Jeremiah 27:18

27:18 I also told them, “If they are really prophets and the Lord is speaking to them, let them pray earnestly to the Lord who rules over all. Let them plead with him not to let the valuable articles that are still left in the Lord’s temple, in the royal palace, and in Jerusalem be taken away to Babylon.
