3 And David smote Hadadezer, the son of Rehob, king of Zobah, as he went to recover his dominion by the river Euphrates. 4 And David took from him one thousand seven hundred horsemen, and twenty thousand footmen; and David houghed all the chariot [horses], but reserved of them [for] a hundred chariots. 5 And the Syrians of Damascus came to help Hadadezer king of Zobah, and David smote of the Syrians twenty-two thousand men. 6 And David put garrisons in Syria of Damascus; and the Syrians became servants to David, [and] brought gifts. And Jehovah preserved David whithersoever he went. 7 And David took the shields of gold that were on the servants of Hadadezer, and brought them to Jerusalem. 8 And from Betah, and from Berothai, cities of Hadadezer, king David took exceeding much bronze.
9 And Toi king of Hamath heard that David had smitten all the forces of Hadadezer; 10 and Toi sent Joram his son to king David, to inquire of his welfare, and to congratulate him, because he had fought against Hadadezer and smitten him; for Hadadezer was continually at war with Toi. And he brought with him vessels of silver, and vessels of gold, and vessels of bronze. 11 Them also king David dedicated to Jehovah, with the silver and the gold that he had dedicated of all the nations that he had subdued: 12 of the Syrians, and of the Moabites, and of the children of Ammon, and of the Philistines, and of the Amalekites, and of the spoil of Hadadezer, the son of Rehob, king of Zobah. 13 And David made him a name when he returned, after he had smitten the Syrians in the valley of salt, eighteen thousand [men]. 14 And he put garrisons in Edom: throughout Edom did he put garrisons; and all they of Edom became servants to David. And Jehovah preserved David whithersoever he went.

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.
