Jeremiah 29:20

Hear ye therefore the word of the Lord
What he was now about to say concerning their false prophets: all ye of the captivity, whom I have sent from Jerusalem to Babylon;
all that were carried captive along with Jeconiah. Some parts of this letter are directed to one sort of the captives, and others to another sort of them; some being good men, some bad; but what follows all are called upon to observe, good and bad; it being a prediction of a certain event, which they would see fulfilled in a short time; and therefore might be of service of them; to the godly, for the confirmation of them in the belief of what the Lord had promised; and to the rest, to make them stop giving heed to false prophets, that should here after arise.
