1 Samuel 28:8-11

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.”

9But the woman said to him, “Surely you know what Saul has done. He has cut off the mediums and spiritists from the land. Why have you set a trap for my life to bring about my death?”

10Saul swore to her by the LORD, “As surely as the LORD lives, you will not be punished for this.”

11Then the woman asked, “Whom shall I bring up for you?” “Bring up Samuel,” he said.
