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.
Matthew Henry's Commentary on 2 Samuel 8:13-14
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.
