1 Samuel 28:4-8

4The Philistines assembled and came and set up camp at Shunem, while Saul gathered all Israel and set up camp at Gilboa. 5When Saul saw the Philistine army, he was afraid; terror filled his heart. 6He inquired of the LORD, but the LORD did not answer him by dreams or Urim or prophets.

7Saul then said to his attendants, “Find me a woman who is a medium, so I may go and inquire of her.” “There is one in Endor,” they said.

8So Saul disguised himself, putting on other clothes, and at night he and two men went to the woman. “Consult a spirit for me,” he said, “and bring up for me the one I name.”
