Deuteronomy 13:3-5

Lexham English Bible

³ you must not listen to the words of that prophet or to that dreamer, for Yahweh your God is testing you to know whether you love^[a] Yahweh your God with all of your heart and with all of your inner self.^{[b] 4} You shall go after Yahweh your God, and him you shall revere, and his commandment you shall keep, and to his voice you shall listen, and him you shall serve, and to him you shall hold fast. ⁵ But that prophet or the dreamer of that dream shall be executed, for he spoke falsely about Yahweh your God, the one bringing you out from the land of Egypt and the one redeeming you from the house of slavery, in order to seduce you from the way that Yahweh your God commanded you to go in it; so in this way you shall purge the evil from your midst.
