1 Samuel 28:3-9

3(Now Samuel was dead, and all Israel had lamented him, and they had buried him in Ramah, even in his own city. And Saul had put away the necromancers and the soothsayers out of the land.)

4And the Philistines gathered themselves together, and came and encamped in Shunem; and Saul gathered all Israel together, and they encamped in Gilboa.

5And when Saul saw the camp of the Philistines, he was afraid, and his heart greatly trembled.

6And Saul inquired of Jehovah; but Jehovah did not answer him, either by dreams, or by Urim, or by prophets.

7Then said Saul to his servants, Seek me a woman that has a spirit of Python, that I may go to her and inquire of her. And his servants said to him, Behold, there is a woman who has a spirit of Python at En-dor.

8And Saul disguised himself, and put on other garments, and he went, and two men with him, and they came to the woman by night; and he said, I pray thee, divine to me by the spirit of Python, and bring me [him] up whom I shall name to thee.

9And the woman said to him, Behold, thou knowest what Saul has done, how he has cut off the necromancers and the soothsayers out of the land; and why layest thou a snare for my life, to cause me to die?
