'Mediums' in the Bible

He made his son into a burnt offering, practiced witchcraft, used divination, and consorted with mediums and spirit-channelers. He practiced many things that the LORD considered to be evil and provoked him.

Furthermore, Josiah removed the mediums, the necromancers, the household gods, the idols, and every despicable thing that could be seen in the territory of Judah and in Jerusalem, so that he might confirm the words of the Law that had been written in the book that Hilkiah the priest had discovered in the LORD's Temple.
