1 Samuel 28:7-8

Then Saul said to his servants, “Find for me a woman who is a medium [between the living and the dead], so that I may go to her and ask her advice.” His servants said to him, “There is a woman who is a medium at En-dor.” So Saul disguised himself by wearing different clothes, and he left with two men, and they came to the woman at night. He said to her, “Conjure up for me, please, and bring up [from the dead] for me [the spirit] whom I shall name to you.”
