1 Samuel 29:2

And the lords of the Philistines passed on by hundreds, and by thousands. — The orderly advance of this great military nation is thus described. The “lords” a different term to the expression “princes.” There were apparently in the Philistine federation five sovereign princes, of whom Achish of Gath was one. Beneath these were other chieftains, who seemingly had great control over the sovereign princes.

David and his men. — David, in return for the lands round Ziklag given him by the King of Gath, seems to have owed a kind of military service to his suzerain Achish. The difference in the arms and equipment of the Israelitish warriors in the division of David, which was marching under the standard of Gath, no doubt excited questions. The general appearance of the Hebrews was, of course, well known to their hereditary Philistine foes.
