Verse 30. "Then the princes of the Philistines went forth" - Probably to avenge themselves on David and the Israelites: but of this war we know no more than that David was more skillful and successful in it than any of the other officers of Saul. His military skill was greater, and his success was proportionate to his skill and courage; hence it is said, he behaved himself more wisely than all the servants of Saul.
