Matthew Henry on 2 Samuel 21:15–end
We have here the story of some conflicts with the Philistines, which happened, as it should seem, in the latter end of David's reign. Though he had so subdued them that they could not bring any great numbers into the field, yet as long as they had any giants among them to be their champions, they would never be quiet, but took all occasions to disturb the peace of Israel, to challenge them, or make incursions upon them.
