1 Samuel 28:6

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

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

⁶  And when Saul inquired of the LORD, the LORD answered him not, neither by dreams, nor by Urim, nor by prophets.

⁷  Then 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 Endor.

⁸  And Saul disguised himself, and put on other raiment, and he went, and two men with him, and they came to the woman by night: and he said, I pray thee, divine unto me by the familiar spirit, and bring me him up, whom I shall name unto thee.
