Jeremiah 27:15

15 for I sent not them, saith the Lord; and they prophesy falsely in my name, that they cast out you, and that ye perish, both ye and the prophets that prophesy to you. (for I did not send them, saith the Lord; and they prophesy falsely in my name, and so I shall cast you out, and ye shall perish, both ye and the prophets who prophesy to you.)

Jeremiah 27:15 Meaning and Commentary

Jeremiah 27:15

For I have not sent them, saith the Lord
See ( Jeremiah 23:21 ) ; yet they prophesy a lie in my name; to deliver out a lie was a very wicked thing, sinful in them, and fatal to others; but to make use of the name of the Lord, and cover it with that, and back it with his authority, was much more wicked and abominable: that I might drive you out, and that ye might perish;
being driven out of their own land, perish in another; which, though the false prophets did not intend by their prophesying, yet such would be, and was, the issue of it: ye, and the prophets that prophesy unto you;
for it would end in the ruin and destruction of them both; both of the false prophets, as the Targum here again calls them, and those that listened to their prophecies; both would fall into the same ditch.

Jeremiah 27:15 In-Context

13 Why shall ye die, thou and thy people, by sword, and hunger, and pestilence, as the Lord spake to the folk, that would not serve to the king of Babylon? (Why shall ye die, thou and thy people, by the sword, and hunger, and pestilence, as the Lord said would happen to any nation, that would not serve the king of Babylon?)

14 Do not ye hear the words of prophets saying to you, Ye shall not serve the king of Babylon; for they speak leasing to you (for they say lies to you),

15 for I sent not them, saith the Lord; and they prophesy falsely in my name, that they cast out you, and that ye perish, both ye and the prophets that prophesy to you. (for I did not send them, saith the Lord; and they prophesy falsely in my name, and so I shall cast you out, and ye shall perish, both ye and the prophets who prophesy to you.)

16 And I spake to the priests, and to this people, and I said, The Lord God saith these things, Do not ye hear the words of your prophets, that prophesy to you, and say, Lo! the vessels of the (house of the) Lord shall turn again now soon from Babylon; for they prophesy a leasing to you. (And I spoke to the priests, and to this people, and I said, The Lord God saith these things, Do not ye listen to the words of your prophets, who prophesy to you, and say, Lo! the vessels of the House of the Lord shall soon be brought back from Babylon; for they prophesy a lie to you.)

17 Therefore do not ye hear them, but serve ye the king of Babylon, that ye live; why is this city given into wilderness? (And so do not ye listen to them, but serve ye the king of Babylon, so that ye can live; why should this city be turned into a wilderness?)
