And that prophet, or that dreamer of dreams, shall be put to death; because he has spoken to turn you away from the LORD your God, which brought you out of the land of Egypt, and redeemed you out of the house of bondage, to thrust you out of the way which the LORD your God commanded you to walk in. So shall you put the evil away from the middle of you.
