Deuteronomy
Chapters 18:19-22
Revised Version 1885
19And 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.
20But the prophet, which 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.
21And if thou say in thine heart, How shall we know the word which the Lord hath not spoken?
22when a prophet speaketh in the name of the Lord, if the thing follow not, nor come to pass, that is the thing which the Lord hath not spoken: the prophet hath spoken it presumptuously, thou shalt not be afraid of him.
