Deuteronomy 18:10-11

Don’t sacrifice your sons or daughters in the fires on your altars. Don’t try to learn what will happen in the future by talking to a fortuneteller or by going to a magician, a witch, or a sorcerer. Don’t let anyone try to put magic spells on other people. Don’t let any of your people become a medium or a wizard. And no one should try to talk with someone who has died.
