Deuteronomy 13:1-5 - The False Prophet
1 If there arise among you a prophet or a dreamer of dreams, and give thee a sign or a wonder - 2 and that sign or wonder which he hath said come to pass - and then say, 'Let us go after strange gods which thou hast not known, and let us serve them': 3 hearken not unto the words of that prophet or dreamer of dreams. For the LORD thy God tempteth you, to wete whether ye love the LORD your God with all your hearts and with all your souls. 4 For ye must walk after the LORD your God and fear him and keep his commandments and hearken unto his voice and serve him and cleave unto him. 5 And that prophet or dreamer of dreams shall die for it, because he hath spoken to turn you away from the LORD your God which brought you out of the land of Egypt and delivered you out of the house of bondage, to thrust thee out of the way which the LORD thy God commanded thee to walk in: and so thou shalt put evil away from thee.
