Deuteronomy 18:11-13

Amplified Bible

¹¹ or one who casts a charm or spell, or a medium, or a spiritist, or a necromancer [who seeks the dead]. ¹² For everyone who does these things is utterly repulsive to the Lord; and because of these detestable practices the Lord your God is driving them out before you. ¹³ You shall be blameless (complete, perfect) before the Lord your God.
