1 Samuel 28:7-9

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

8And Saul disguised himself, and put on other raiment, and went, he and two men with him, and they came to the woman by night: and he said, Divine unto me, I pray thee, by the familiar spirit, and bring me up whomsoever I shall name unto thee. 9And the woman said unto him, Behold, thou knowest what Saul hath done, how he hath cut off those that have familiar spirits, and the wizards, out of the land: wherefore then layest thou a snare for my life, to cause me to die?
