3 Moreover, David defeated Hadadezer son of Rehob, king of Zobah, when he went to restore his monument at[1] the Euphrates River. 4 David captured a thousand of his chariots, seven thousand charioteers[2] and twenty thousand foot soldiers. He hamstrung all but a hundred of the chariot horses. 5 When the Arameans of Damascus came to help Hadadezer king of Zobah, David struck down twenty-two thousand of them. 6 He put garrisons in the Aramean kingdom of Damascus, and the Arameans became subject to him and brought tribute. The Lord gave David victory wherever he went. 7 David took the gold shields that belonged to the officers of Hadadezer and brought them to Jerusalem. 8 From Tebah[3] and Berothai, towns that belonged to Hadadezer, King David took a great quantity of bronze.

9 When Tou[4] king of Hamath heard that David had defeated the entire army of Hadadezer, 10 he sent his son Joram[5] to King David to greet him and congratulate him on his victory in battle over Hadadezer, who had been at war with Tou. Joram brought with him articles of silver, of gold and of bronze. 11 King David dedicated these articles to the Lord, as he had done with the silver and gold from all the nations he had subdued: 12 Edom[6] and Moab, the Ammonites and the Philistines, and Amalek. He also dedicated the plunder taken from Hadadezer son of Rehob, king of Zobah. 13 And David became famous after he returned from striking down eighteen thousand Edomites[7] in the Valley of Salt. 14 He put garrisons throughout Edom, and all the Edomites became subject to David. The Lord gave David victory 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.
