Deuteronomy 18:9-13

“When you enter the land which the LORD your God is giving you, you shall not learn to imitate the detestable (repulsive) practices of those nations. There shall not be found among you anyone who makes his son or daughter pass through the fire [as a sacrifice], one who uses divination and fortune-telling, one who practices witchcraft, or one who interprets omens, or a sorcerer, or one who casts a charm or spell, or a medium, or a spiritist, or a necromancer [who seeks the dead]. 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. You shall be blameless (complete, perfect) before the LORD your God.
