1 Samuel 29:3 And the heads of the Philistines say, `What `are' these Hebrews?' and Achish saith unto the heads of the Philistines, `Is not this David servant of Saul king of Israel, who hath been with me these days or these years, and I have not found in him anything `wrong' from the day of his falling away till this day.' (Young's Literal Translation)
