3 David also struck down King Hadadezer son of Rehob of Zobah, as he went to restore his monument at the river Euphrates. 4 David took from him one thousand seven hundred horsemen, and twenty thousand foot soldiers. David hamstrung all the chariot horses, but left enough for a hundred chariots. 5 When the Arameans of Damascus came to help King Hadadezer of Zobah, David killed twenty-two thousand men of the Arameans. 6 Then David put garrisons among the Arameans of Damascus; and the Arameans became servants to David and brought tribute. The Lord gave victory to David wherever he went. 7 David took the gold shields that were carried by the servants of Hadadezer, and brought them to Jerusalem. 8 From Betah and from Berothai, towns of Hadadezer, King David took a great amount of bronze.
9 When King Toi of Hamath heard that David had defeated the whole army of Hadadezer, 10 Toi sent his son Joram to King David, to greet him and to congratulate him because he had fought against Hadadezer and defeated him. Now Hadadezer had often been at war with Toi. Joram brought with him articles of silver, gold, and bronze; 11 these also King David dedicated to the Lord, together with the silver and gold that he dedicated from all the nations he subdued, 12 from Edom, Moab, the Ammonites, the Philistines, Amalek, and from the spoil of King Hadadezer son of Rehob of Zobah. 13 David won a name for himself. When he returned, he killed eighteen thousand Edomites in the Valley of Salt.

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.
