1 Samuel 28:3-9

3Now Samuel had died, and all Israel had lamented for him and buried him in Ramah, in his own city. And Saul had put the mediums and the spiritists out of the land.

4Then the Philistines gathered together, and came and encamped at Shunem. So Saul gathered all Israel together, 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 the prophets.

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?”
