1 Samuel 28:3-11

Now Samuel had died, and all Israel had mourned for him and buried him in Ramah, his own city. Saul had expelled the mediums and the wizards from the land. The Philistines assembled, and came and encamped at Shunem. Saul gathered all Israel, and they encamped at Gilboa. When Saul saw the army of the Philistines, he was afraid, and his heart trembled greatly. When Saul inquired of the LORD, the LORD did not answer him, not by dreams, or by Urim, or by prophets. 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.” The woman said to him, “Surely you know what Saul has done, how he has cut off the mediums and the wizards from the land. Why then are you laying a snare for my life to bring about my death?” But Saul swore to her by the LORD, “As the LORD lives, no punishment shall come upon you for this thing.” Then the woman said, “Whom shall I bring up for you?” He answered, “Bring up Samuel for me.”
