1 Samuel 28:7-8

Then Saul said to his servants, Find me a woman who is a medium [between the living and the dead], that I may go and inquire of her. His servants said, Behold, there is a woman who is a medium at Endor. So Saul disguised himself, put on other raiment, and he and two men with him went and came to the woman at night. He said to her, Perceive for me by the familiar spirit and bring up for me the dead person whom I shall name to you.
