Devarim 13:5

And that navi, or that dreamer of dreams, shall be put to death; because he hath spoken to turn you away from HASHEM Eloheichem, which brought you out of Eretz Mitzrayim, and redeemed you out of the bais avadim, to entice thee from HaDerech which HASHEM Eloheicha commanded thee to walk in. So shalt thou put harah away from the midst of thee.
