Deuteronomy 18:10-13

For example, never sacrifice your son or daughter as a burnt offering. And do not let your people practice fortune-telling, or use sorcery, or interpret omens, or engage in witchcraft, or cast spells, or function as mediums or psychics, or call forth the spirits of the dead. Anyone who does these things is detestable to the LORD. It is because the other nations have done these detestable things that the LORD your God will drive them out ahead of you. But you must be blameless before the LORD your God.
