John Gill Commentary Jeremiah 27:16

"Also I spake to the priests and to all this people, saying, Thus saith Jehovah: Hearken not to the words of your prophets that prophesy unto you, saying, Behold, the vessels of Jehovah`s house shall now shortly be brought again from Babylon; for they prophesy a lie unto you." — Jeremiah 27:16 (ASV)

Also I spoke to the priests, and to all this people, saying, &c.] From the court he went to the temple, and spoke to the priests that were ministering there, and to all the people that were assembled for divine worship; either at the ordinary time of it, or at some one of the solemn feasts: this was a proper time and place to meet with the people and the priests; which latter especially had a concern in what he had to say concerning the vessels of the temple.

Thus says the Lord, hearken not to the words of your prophets that prophesy unto you: your false prophets, as the Targum: saying; as follows:

Behold, the vessels of the Lord's house shall now shortly be brought again from Babylon; which were carried thither, both in the times of Jehoiakim, and of Jeconiah, (2 Chronicles 36:7 2 Chronicles 36:10); these the false prophets gave out would in a short time be returned; that the king of Babylon, either willingly and of his own accord, or being pressed or forced to it, would send them back; so little reason had they to fear an invasion from him, or captivity by him:

For they prophesy a lie unto you; that which is false, and will never be accomplished, at least in any short time.
