Deuteronomy 18:15-20 American Standard Version (ASV)
15 Jehovah thy God will raise up unto thee a prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken; 16 according to all that thou desiredst of Jehovah thy God in Horeb in the day of the assembly, saying, Let me not hear again the voice of Jehovah my God, neither let me see this great fire any more, that I die not. 17 And Jehovah said unto me, They have well said that which they have spoken. 18 I will raise them up a prophet from among their brethren, like unto thee; and I will put my words in his mouth, and he shall speak unto them all that I shall command him. 19 And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.
20 But the prophet, that shall speak a word presumptuously in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, that same prophet shall die.
