'Mediums' in the Bible
" 'You shall not turn to the mediums and to the soothsayers; you shall not seek [them] to become unclean with them; I [am] Yahweh your God.
As for the person who turns to the mediums and the soothsayers to prostitute after them, I will set my face against that person, and I will cut him off from the midst of his people.
(Now Samuel had died, and all Israel had mourned for him, and they had buried him in Ramah, his [own] city. And Saul had expelled the mediums and the soothsayers from the land.)
But the woman said to him, "Look, you know what Saul did, how he exterminated the mediums and the soothsayers from the land! Why [are] you setting a trap for my life to kill me?"

Moreover, the mediums and the spiritists, the household gods and the idols, and all of the abominations that were seen in the land of Judah and in Jerusalem, Josiah removed in order to establish the words of the law written on the scroll that Hilkiah the priest had found [in] the temple of Yahweh.
And he himself burned his sons in the fire in the Valley of Ben-Hinnom. And he practiced sorcery and divination, and he engaged in witchcraft and dealt with mediums and spiritists. And he did much evil in the eyes of Yahweh, to provoke him to anger.
