Jeremiah 14:14-15

14Then the Lord said to me, “The [counterfeit] prophets are prophesying lies in My Name. I have neither sent them nor authorized them nor spoken to them. They are prophesying to you made-up visions [pretending to call forth responses from handmade gods], a worthless divination and the deceit of their own mind.

15Therefore, thus says the Lord concerning the [false] prophets who are prophesying in My Name, although I did not send them—yet they keep saying, ‘Sword and famine shall not be in this land’: by sword and famine those prophets shall meet their end and be consumed.
