Jeremiah 14:14-15
14
Then Yahweh said to me, The prophets prophesy lies in my name; I didn't send them, neither have I commanded them, neither spoke I to them: they prophesy to you a lying vision, and divination, and a thing of nothing, and the deceit of their own heart.
15
Therefore thus says Yahweh concerning the prophets who prophesy in my name, and I didn't send them, yet they say, Sword and famine shall not be in this land: By Sword and famine shall those prophets be consumed.
