Deuteronomy 18:19-21

Living Bible

¹⁹ I will personally deal with anyone who will not listen to him and heed his messages from me. ²⁰ But any prophet who falsely claims that his message is from me shall die. And any prophet who claims to give a message from other gods must die.’ ²¹ If you wonder, ‘How shall we know whether the prophecy is from the Lord or not?’
