81 And it cometh to pass afterwards that David smiteth the Philistines, and humbleth them, and David taketh the bridle of the metropolis out of the hand of the Philistines. 2 And he smiteth Moab, and measureth them with a line, causing them to lie down on the earth, and he measureth two lines to put to death, and the fulness of the line to keep alive, and the Moabites are to David for servants, bearers of a present. 3 And David smiteth Hadadezer son of Rehob, king of Zobah, in his going to bring back his power by the River 'Euphrates;' 4 and David captureth from him a thousand and seven hundred horsemen, and twenty thousand footmen, and David destroyeth utterly the whole of the charioteers, only he leaveth of them a hundred charioteers. 5 And Aram of Damascus cometh to give help to Hadadezer king of Zobah, and David smiteth of Aram twenty and two thousand men; 6 and David putteth garrisons in Aram of Damascus, and Aram is to David for a servant, bearing a present; and Jehovah saveth David whithersoever he hath gone; 7 and David taketh the shields of gold which were on the servants of Hadadezer, and bringeth them to Jerusalem; 8 and from Betah, and from Berothai, cities of Hadadezer, hath king David taken very much brass.
9 And Toi king of Hamath heareth that David hath smitten all the force of Hadadezer, 10 and Toi sendeth Joram his son unto king David to ask of him of welfare, and to bless him, (because that he hath fought against Hadadezer, and smiteth him, for a man of wars 'with' Toi had Hadadezer been), and in his hand have been vessels of silver, and vessels of gold, and vessels of brass, 11 also them did king David sanctify to Jehovah, with the silver and the gold which he sanctified of all the nations which he subdued: 12 of Aram, and of Moab, and of the Bene-Ammon, and of the Philistines, and of Amalek, and of the spoil of Hadadezer son of Rehob king of Zobah. 13 And David maketh a name in his turning back from his smiting Aram in the valley of Salt—eighteen thousand; 14 and he putteth in Edom garrisons—in all Edom he hath put garrisons, and all Edom are servants to David; and Jehovah saveth David whithersoever he hath gone.
15 And David reigneth over all Israel, and David is doing judgment and righteousness to all his people,
Matthew Henry's Commentary on 2 Samuel 8:1-15
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.
Commentary on 2 Samuel 8:15-18
(Read 2 Samuel 8:15-18)
David neither did wrong, nor denied or delayed right to any. This speaks his close application to business; also his readiness to admit all addresses and appeals made to him. He had no respect of persons in judgment. Herein he was a type of Christ. To Him let us submit, his friendship let us seek, his service let us count our pleasure, diligently attending to the work he assigns to each of us. David made his sons chief rulers; but all believers, Christ's spiritual seed, are better preferred, for they are made kings and priests to our God, Revelation 1:6.
