1 Samuel 28:5-7

King James Version

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

⁶ And when Saul enquired 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 enquire of her. And his servants said to him, Behold, there is a woman that hath a familiar spirit at Endor.
