Deuteronomy 18:12-22

18:12 Whoever does these things is abhorrent to the Lord and because of these detestable things the Lord your God is about to drive them out from before you. 18:13 You must be blameless before the Lord your God. 18:14 Those nations that you are about to dispossess listen to omen readers and diviners, but the Lord your God has not given you permission to do such things.

18:15 The Lord your God will raise up for you a prophet like me from among you – from your fellow Israelites; you must listen to him. 18:16 This accords with what happened at Horeb in the day of the assembly. You asked the Lord your God: “Please do not make us hear the voice of the Lord our God any more or see this great fire any more lest we die.” 18:17 The Lord then said to me, “What they have said is good. 18:18 I will raise up a prophet like you for them from among their fellow Israelites. I will put my words in his mouth and he will speak to them whatever I command. 18:19 I will personally hold responsible anyone who then pays no attention to the words that prophet speaks in my name.

18:20 “But if any prophet presumes to speak anything in my name that I have not authorized him to speak, or speaks in the name of other gods, that prophet must die. 18:21 Now if you say to yourselves, ‘How can we tell that a message is not from the Lord?’ – 18:22 whenever a prophet speaks in my name and the prediction is not fulfilled, then I have not spoken it; the prophet has presumed to speak it, so you need not fear him.”
