Commentaries
8:1-8. David subdued the Philistines. They had long been troublesome to Israel. And after the long and frequent struggles the saints have with the powers of darkness, like Israel with the Philistines, the Son of David shall tread them all under foot, and make the saints more than conquerors. He smote the Moabites, and made them tributaries to Israel. Two parts he destroyed, the third part he spared. The line that was to keep alive, though it was but one, is ordered to be a full line. Let the line of mercy be stretched to the utmost. He smote the Syrians. In all these wars David was protected, for this in his psalms he often gives glory to God.
CHAPTER 8
2Sa 8:1, 2. David Subdues the Philistines, and Makes the Moabites Tributary.
1. David took Metheg-ammah out of the hand of the Philistines—that is, Gath and her suburban towns (1Ch 18:1). That town had been "a bridle" by which the Philistines kept the people of Judah in check. David used it now as a barrier to repress that restless enemy.
