When you enter the land the Lord your God is giving you, do not learn to imitate the detestable ways of the nations there. ¹⁰ Let 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, ¹¹ or casts spells, or who is a medium or spiritist or who consults the dead. ¹² 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. ¹³ You must be blameless before the Lord your God.¹⁴ The nations you will dispossess listen to those who practice sorcery or divination.  But as for you, the Lord your God has not permitted you to do so.

(Deuteronomy 18:9-14 -- NIV)
