1 Samuel 29:6-8

Young's Literal Translation

⁶ And Achish calleth unto David, and saith unto him, `Jehovah liveth, surely thou [art] upright, and good in mine eyes is thy going out, and thy coming in, with me in the camp, for I have not found in thee evil from the day of thy coming in unto me till this day; and in the eyes of the princes thou art not good;

⁷ and now, turn back, and go in peace, and thou dost do no evil in the eyes of the princes of the Philistines.'

⁸ And David saith unto Achish, `But what have I done? and what hast thou found in thy servant from the day that I have been before thee till this day -- that I go not in and have fought against the enemies of my lord the king?'
