1 Samuel 28:20-22

Young's Literal Translation

²⁰ And Saul hasteth and falleth -- the fulness of his stature -- to the earth, and feareth greatly because of the words of Samuel; also power was not in him, for he had not eaten bread all the day, and all the night.

²¹ And the woman cometh in unto Saul, and seeth that he hath been greatly troubled, and saith unto him, `Lo, thy maid-servant hath hearkened to thy voice, and I put my soul in my hand, and I obey thy words which thou hast spoken unto me;

²² and now, hearken, I pray thee, also thou, to the voice of thy maid-servant, and I set before thee a morsel of bread, and eat, and there is in thee power when thou goest in the way.'
