Deuteronomy 18:10-14

10There 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,

11or one who casts a charm or spell, or a medium, or a spiritist, or a necromancer [who seeks the dead].

12For 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.

13You shall be blameless (complete, perfect) before the Lord your God.

14For these nations which you shall dispossess listen to those who practice witchcraft and to diviners and fortune-tellers, but as for you, the Lord your God has not allowed you to do so.
