Deuteronomy 18:10-12

10Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, 11or casts spells, or who is a medium or spiritist or who consults the dead. 12Anyone who does these things is detestable to the LORD ; because of these same detestable practices the LORD your God will drive out those nations before you.
