Jeremiah 14:14-15

14The Lord said to me, ‘Those prophets say that they speak my messages, but they are telling lies. I did not send them. I did not give them my authority. I did not give them any messages. They are deceiving people with the visions that they talk about. When they prophesy about things, it means nothing. They only speak about their own foolish ideas.

15They claim to speak with my authority, but I did not send them. They say that there will be no war or famine. So I tell you, this is what will happen to those prophets: War and famine will kill them.
