6 Then he placed several army garrisons in Damascus, the Aramean capital, and the Arameans became David's subjects and paid him tribute money. So the Lord made David victorious wherever he went.

Matthew Henry's Commentary on 2 Samuel 8:6

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.
