1 Samuel 29:1-3

Young's Literal Translation

29 And the Philistines gather all their camps to Aphek, and the Israelites are encamping at a fountain which [is] in Jezreel,

² and the princes of the Philistines are passing on by hundreds, and by thousands, and David and his men are passing on in the rear with Achish.

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.'
