3 And David overcame Hadadezer, the son of Rehob, king of Zobah, when he went to make his power seen by the River. 4 And David took from him one thousand, seven hundred horsemen and twenty thousand footmen: and David had the leg-muscles of the horses cut, only keeping enough of them for a hundred war-carriages. 5 And when the Aramaeans of Damascus came to the help of Hadadezer, king of Zobah, David put to the sword twenty-two thousand of the Aramaeans. 6 And David put armed forces in Aram of Damascus: and the Aramaeans became servants to David and gave him offerings. And the Lord made David overcome wherever he went. 7 And David took their gold body-covers from the servants of Hadadezer and took them to Jerusalem. 8 And from Tebah and Berothai, towns of Hadadezer, King David took a great store of brass.

9 And when Tou, king of Hamath, had news that David had overcome all the army of Hadadezer, 10 He sent his son Hadoram to David, with words of peace and blessing, because he had overcome Hadadezer in the fight, for Hadadezer had wars with Tou; and Hadoram took with him vessels of silver and gold and brass: 11 These King David made holy to the Lord, together with the silver and gold which he had taken from the nations he had overcome— 12 The nations of Edom and Moab, and the children of Ammon and the Philistines and the Amalekites and the goods he had taken from Hadadezer, the son of Rehob, king of Zobah. 13 And David got great honour for himself, when he came back, by the destruction of Edom in the valley of Salt, to the number of eighteen thousand men. 14 And he put armed forces in Edom; all through Edom he had armed forces stationed, and all the Edomites became servants to David. And the Lord made David overcome 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.
