Jeremiah 14:15

Therefore thus saith the Lord concerning the prophets
The false prophets, as the following description shows: that prophecy in my name, and I sent them not;
made use of his name, pretending his authority, though they were not sent by him: yet they say, sword and famine shall not be in the land;
though the Lord by his true prophet had said there should be both; which proves that they were not sent by the Lord, since what they said was in direct opposition to the word of the Lord; wherefore their doom in righteous judgment follows: by sword and famine shall these prophets be consumed;
they should be some of the first, if not the first that should perish by these calamities; which would abundantly prove the falsehood of their predictions, and show that their lies could neither secure themselves nor others from the judgments which the Lord had said should come upon them.
