1 Samuel 28:7-8

7Saul then said to his servants, “Find me a woman who is a medium, so I can go and consult her.” His servants replied, “There is a woman at En-dor who is a medium.”

8Saul disguised himself by putting on different clothes and 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 tell you.”
