Deuteronomy 18:9-14 NRSV
When you come into the land that the LORD your God is giving you, you must not learn to imitate the abhorrent practices of those nations. No one shall be found among you who makes a son or daughter pass through fire, or who practices divination, or is a soothsayer, or an augur, or a sorcerer, or one who casts spells, or who consults ghosts or spirits, or who seeks oracles from the dead. For whoever does these things is abhorrent to the LORD; it is because of such abhorrent practices that the LORD your God is driving them out before you. You must remain completely loyal to the LORD your God. Although these nations that you are about to dispossess do give heed to soothsayers and diviners, as for you, the LORD your God does not permit you to do so.
