13:1If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,

13:2And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them;

18:21And if thou say in thine heart, How shall we know the word which the LORD hath not spoken?

18:22When 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, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.
