1 Samuel 28:6-7

28:6 So Saul inquired of the Lord, but the Lord did not answer him – not by dreams nor by Urim nor by the prophets. 28:7 So Saul instructed his servants, “Find me a woman who is a medium, so that I may go to her and inquire of her.” His servants replied to him, “There is a woman who is a medium in Endor.”
