1 Samuel 28:7-8

Then Saul said to his servants, “Seek out for me a woman who is a medium, so that I may go to her and inquire of her.” His servants said to him, “There is a medium at Endor.” So Saul disguised himself and put on other clothes and went there, he and two men with him. They came to the woman by night. And he said, “Consult a spirit for me, and bring up for me the one whom I name to you.”
