'Medium' in the Bible

So Saul said to his servants, "Search for me {a woman who is a medium} so that I may go to her and inquire of her." His servants said to him, "Look [there is] a woman who [is] a medium in Endor."

So Saul died on account of his sin which he had sinned against Yahweh concerning the command of Yahweh that he did not keep. He also consulted a medium to seek [guidance].
