Death to False Prophets

But any prophet who claims to give a message from another god or who falsely claims to speak for me must die.’  You may wonder, ‘How will we know whether the prophecy is from the LORD or not?’  If the prophet predicts something in the LORD’s name and it does not happen, the LORD did not give the message.  That prophet has spoken on his own and need not be feared.  (Deuteronomy 18:20-22 NLT)
