'Mediums' in the Bible

He made his son pass through the fire, practiced witchcraft and used divination, and dealt with mediums and spiritists. He did much evil in the sight of the Lord provoking Him to anger.

Moreover, Josiah removed the mediums and the spiritists and the teraphim and the idols and all the abominations that were seen in the land of Judah and in Jerusalem, that he might confirm the words of the law which were written in the book that Hilkiah the priest found in the house of the Lord.
