1 Samuel 28:8

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.

⁹  And 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?

¹⁰  And Saul sware to her by the LORD, saying, As the LORD liveth, there shall no punishment happen to thee for this thing.
