3 David also destroyed the forces of Hadadezer son of Rehob, king of Zobah, when Hadadezer marched out to strengthen his control along the Euphrates River. 4 David captured 1,000 chariots, 7,000 charioteers, and 20,000 foot soldiers. He crippled all the chariot horses except enough for 100 chariots. 5 When Arameans from Damascus arrived to help King Hadadezer, David killed 22,000 of them. 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. 7 David brought the gold shields of Hadadezer's officers to Jerusalem, 8 along with a large amount of bronze from Hadadezer's towns of Tebah and Berothai.

9 When King Toi of Hamath heard that David had destroyed the entire army of Hadadezer, 10 he sent his son Joram to congratulate King David for his successful campaign. Hadadezer and Toi had been enemies and were often at war. Joram presented David with many gifts of silver, gold, and bronze. 11 King David dedicated all these gifts to the Lord, as he did with the silver and gold from the other nations he had defeated- 12 from Edom, Moab, Ammon, Philistia, and Amalek-and from Hadadezer son of Rehob, king of Zobah. 13 So David became even more famous when he returned from destroying 18,000 Edomites in the Valley of Salt. 14 He placed army garrisons throughout Edom, and all the Edomites became David's subjects. In fact, the Lord made David victorious wherever he went.

Matthew Henry's Commentary on 2 Samuel 8:3-14

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.

Commentary on 2 Samuel 8:9-14

(Read 2 Samuel 8:9-14)

All the precious things David was master of, were dedicated things; they were designed for building the temple. The idols of gold David destroyed, 2 Samuel 5:21, but the vessels of gold he dedicated. Thus, in the conquest of a soul by the grace of the Son of David, what stands in opposition to God must be destroyed, every lust must be mortified and crucified, but what may glorify him must be dedicated; thus the property of it is altered. God employs his servants in various ways; some, as David, in spiritual battles; others, as Solomon, in spiritual buildings; and one prepares work for the other, that God may have the glory of all.
