Deuteronomy 18:9-12

When you enter the land the LORD your God is giving you, do not learn to imitate the detestable ways of the nations there. Let no-one be found among you who sacrifices their son or daughter in the fire, who practises divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead. Anyone 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.
