29:2 When the leaders of the Philistines were passing in review at the head of their units of hundreds and thousands, David and his men were passing in review in the rear with Achish.

29:3 The leaders of the Philistines asked, “What about these Hebrews?” Achish said to the leaders of the Philistines, “Isn’t this David, the servant of King Saul of Israel, who has been with me for quite some time? I have found no fault with him from the day of his defection until the present time!”
