1 Samuel 28:7-13

7Then Saul said to his servants, “Find me a woman who is a medium, that I may go to her and inquire of her.” And his servants said to him, “In fact, there is a woman who is a medium at En Dor.”

8So Saul disguised himself and put on other clothes, and he went, and two men with him; and they came to the woman by night. And he said, “Please conduct a séance for me, and bring up for me the one I shall name to you.”

9Then the woman said to him, “Look, you know what Saul has done, how he has cut off the mediums and the spiritists from the land. Why then do you lay a snare for my life, to cause me to die?”

10And Saul swore to her by the Lord, saying, “As the Lord lives, no punishment shall come upon you for this thing.”

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

12When the woman saw Samuel, she cried out with a loud voice. And the woman spoke to Saul, saying, “Why have you deceived me? For you are Saul!”

13And the king said to her, “Do not be afraid. What did you see?” And the woman said to Saul, “I saw a spirit ascending out of the earth.”
