Jeremiah 27:14, 18

Do not listen to and believe the words of the [false] prophets who are saying to you, ‘You will not serve the king of Babylon,’ for they prophesy a lie to you

But if they are [true] prophets, and if the word of the LORD is [really spoken] by them, let them now entreat the LORD of hosts that the articles which are [still] left in the house of the LORD, in the house of the king of Judah and in Jerusalem may not go to Babylon.
