Deuteronomy 13:5

CLV(i) 5 Then that prophet or that dreamer of dreams shall be put to death because he spoke of defection from Yahweh your Elohim (the One bringing you forth from the country of Egypt and the One ransoming you from the house of servants) so as to induce you from the way in which Yahweh your Elohim has instructed you to walk. Hence eradicate the evil from among you.
