Deuteronomy 18:9-14

When you enter the land the LORD your God is giving you, you must not learn the abhorrent practices of those nations. There must never be found among you anyone who sacrifices his son or daughter in the fire, anyone who practices divination, an omen reader, a soothsayer, a sorcerer, one who casts spells, one who conjures up spirits, a practitioner of the occult, or a necromancer. Whoever does these things is abhorrent to the LORD and because of these detestable things the LORD your God is about to drive them out from before you. You must be blameless before the LORD your God. Those nations that you are about to dispossess listen to omen readers and diviners, but the LORD your God has not given you permission to do such things.
