81 In the days that followed, David struck hard at the Philistines - brought them to their knees and took control of the countryside. 2 He also fought and defeated Moab. He chose two-thirds of them randomly and executed them. The other third he spared. So the Moabites fell under David's rule and were forced to bring tribute. 3 On his way to restore his sovereignty at the River Euphrates, David next defeated Hadadezer son of Rehob the king of Zobah. 4 He captured from him a thousand chariots, seven thousand cavalry, and twenty thousand infantry. He hamstrung all the chariot horses, but saved back a hundred. 5 When the Arameans from Damascus came to the aid of Hadadezer king of Zobah, David killed twenty-two thousand of them. 6 David set up a puppet government in Aram-Damascus. The Arameans became subjects of David and were forced to bring tribute. God gave victory to David wherever he marched. 7 David plundered the gold shields that belonged to the servants of Hadadezer and brought them to Jerusalem. 8 He also looted a great quantity of bronze from Tebah and Berothai, cities of Hadadezer.

Commentary on 2 Samuel 8:1-8.
(Read 2 Samuel 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.
