“And if thou say in thine heart, How shall wee know the word which the Lord hath not spoken?”
King James Version (KJV)
18. I will raise them vp a Prophet from among their brethren, like vnto thee, and will put my wordes in his mouth, and hee shall speake vnto them all that I shall command him. 19. And it shall come to passe, that whosoeuer will not hearken vnto my words, which hee shall speake in my name, I will require it of him. 20. But the prophet which shall presume to speake a word in my name, which I haue not commanded him to speake, or that shall speake in the name of other gods, euen that prophet shall die. 21. And if thou say in thine heart, How shall wee know the word which the Lord hath not spoken? 22. When a prophet speaketh in the name of the Lord, if the thing follow not, nor come to passe, that is the thing which the Lord hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not bee afraid of him.
