Deuteronomy 18:17-22

And Jehovah said unto me, They have well said that which they have spoken. 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. 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. 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. And if thou say in thy heart, How shall we know the word which Jehovah hath not spoken? when a prophet speaketh in the name of Jehovah, if the thing follow not, nor come to pass, that is the thing which Jehovah hath not spoken: the prophet hath spoken it presumptuously, thou shalt not be afraid of him.
