1 Samuel 28:3–10

³Now Samuel had died, and all Israel had mourned for him and buried him in Ramah, his own city. And Saul had put the mediums and the wizards out of the land. ⁴The Philistines assembled, and came and encamped at Shunem; and Saul gathered all Israel, and they encamped at Gilboa. ⁵When Saul saw the army of the Philistines, he was afraid, and his heart trembled greatly. ⁶And when Saul inquired of the Lord, the Lord did not answer him, either by dreams, or by Urim, or by prophets. ⁷Then Saul said to his servants, “Seek out for me a woman who is a medium, that I may go to her and inquire of her.” And his servants said to him, “Behold, there is a medium at Endor.”

⁸So Saul disguised himself and put on other garments, and went, he and two men with him; and they came to the woman by night. And he said, “Divine for me by a spirit, and bring up for me whomever I shall name to you.” ⁹The 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?” ¹⁰But Saul swore to her by the Lord, “As the Lord lives, no punishment shall come upon you for this thing.”
