1 Samuel 28:7-8

Then Saul said to his servants, “Find me a woman who is a medium, so I can go and consult her.” “There is a medium at Endor,” his servants replied. So Saul disguised himself by putting on different clothes, and he set out with two of his men. They came to the woman at night, and Saul said, “Consult a spirit for me. Bring up for me the one I name.”
