Here is, 1. The court made to David by the king of Hamath, who, it seems was at this time at war with the king of Zobah. He hearing of David's success against his enemy, sent his own son ambassador to him (Sa2 8:9, Sa2 8:10), to congratulate him on his victory, to return him thanks for the favour he had done him in breaking the power of one he was in fear of, and to beg his friendship. Thus he not only secured but strengthened himself. And David lost nothing by taking this little prince under his protection, any more than the old Romans did by the like policy; for the wealth he had from the countries he conquered by way of spoil he had from this by way of present or gratuity: Vessels of silver and gold. Better get by composition than by compulsion. 2. The offering David made to God of the spoils of the nations and all the rich things that were brought him. He dedicated all to the Lord, Sa2 8:11, Sa2 8:12. This crowned all his victories, and made them far to out-shine Alexander's or Caesar's, that they sought their own glory, but he aimed at the glory of God. All the precious things he was master of were dedicated things, that is, they were designed for the building of the temple; and a good omen it was of kindness to the Gentiles in the fulness of time, and of the making of God's house a house of prayer for all people, that the temple was built of the spoils and presents of Gentile nations, in allusion to which we find the kings of the earth bringing their glory and honour into the new Jerusalem, Rev 21:24. Their gods of gold David burnt (Sa2 5:21), but their 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 mortified and crucified, but what may glorify him must be dedicated and the property of it altered. Even the merchandise and the hire must be holiness to the Lord (Isa 23:18), the gain consecrated to the Lord of the whole earth (Mic 4:13), and then it is truly our own and that most comfortably. 3. The reputation he got, in a particular manner, by his victory over the Syrians and their allies the Edomites, who acted in conjunction with them, as appears by comparing the title of the 60th Psalm, which was penned on this occasion, with Sa2 8:13. He got himself a name for all that conduct and courage which are the praise of a great and distinguished general. Something extraordinary, it is likely, there was in that action, which turned very much to his honour, yet he is careful to transfer the honour to God, as appears by the psalm he penned on this occasion, Sa2 8:12. It is through God that we do valiantly. 4. His success against the Edomites. They all became David's servants, Sa2 8:14. Now, and not till now, Isaac's blessing was accomplished, by which Jacob was made Esau's Lord (Gen 27:37-40) and the Edomites continued long tributary to the kings of Judah, as the Moabites were to the kings of Israel, till, in Joram's time, they revolted (Ch2 21:8) as Isaac had there foretold that Esau should, in process of time, break the yoke from off his neck. Thus David by his conquests, (1.) Secured peace to his son, that he might have time to build the temple. And, (2.) Procured wealth for his son, that he might have wherewith to build it. God employs his servants variously, some in one employment, others in another, some in the spiritual battles, others in the spiritual buildings; and one prepares work for the other, that God may have the glory of all. All David's victories were typical of the success of the gospel against the kingdom of Satan, in which the Son of David rode forth, conquering and to conquer, and he shall reign till he has brought down all opposing rule, principality, and power: and he has, as David had (Sa2 8:2), a line to kill and a line to save; for the same gospel is to some a savour of life unto life, to others a savour of death unto death.

David gat him a name - Became a very celebrated and eminent man. The Targum has it, David collected troops; namely, to recruit his army when he returned from smiting the Syrians. His many battles had no doubt greatly thinned his army.

The valley of salt - Supposed to be a large plain abounding in this mineral, about a league from the city of Palmyra or Tadmor in the wilderness.

And David gat him a name,.... Fame and reputation in the several nations of the world for valour and courage, for the many and signal victories that he obtained; the Jewish writers generally refer this to his humanity in burying the dead bodies of his enemies slain in war, which gained him great esteem among all, and even his very enemies; but nothing of that kind is pointed at here, but his conquests: or "he made himself a name"; erected a triumphal arch (b) in memory of his victories:

when he returned from smiting of the Syrians in the valley of salt,

being eighteen thousand men; in the relation of this fact in different places some difficulties arise, both as to the people smitten, and their numbers, and by whom; in this place they are said to be Syrians, but in Ch1 18:12, and in the title of Psa 60:1, which was composed on account of these victories, they are called Edomites, and said to be of Edom; which may be reconciled by observing, that the Syrians and Edomites were confederates in this war; and that whereas the latter were auxiliaries to the former, the whole body of the army might be called Syrians, of which twenty two thousand were slain that were properly Syrians, and eighteen thousand Edomites, in all forty thousand; which was a very great slaughter: or the sense is, that when he had smitten the twenty two thousand Syrians, and was upon the return, he met with a body of Edomites, who came to the assistance of the Syrians, and he slew eighteen thousand of them; and the Jews say, as Jarchi observes, there were two battles; and if so, this would remove all the difficulties started; as for the numbers slain, here eighteen thousand, and Psa 60:1, twelve thousand, it is reconciled by observing, that Abishai first began the attack upon the Edomites, and slew six thousand of them; and then Joab fell upon them, and slew twelve thousand more, in all eighteen thousand; in Ch1 18:12, this slaughter is ascribed to Abishai, because he began it, even the whole number; and in Psa 60:1, to Joab, the twelve thousand slain by him, who seconded Abishai; and the whole is here attributed to David, because he was king, under whom Abishai and Joab served as generals: and no less difficult is it to ascertain the place where this slaughter was made, called "the valley of salt": it seems by our text that it was in Syria, but in other places as if it was in Edom; see Kg2 14:7; but in Edom itself is no such valley to be found, though there is in Syria; one traveller (c) tells us, that in the way from Aleppo to the banks of Euphrates are many villages, among which is one of note, called Tedith, famous for a synod held here by the Jews, in the year from the creation 3498, of which Ezra was the scribe; when were placed the books of the Old Testament in the order in which they now are; and near this town, he says, is the valley of salt, memorable for the victory here recorded: others say (d) about three or four hours' journey from Aleppo is the valley of salt, near which is a salt spring, whose waters running over the place leave, when dried by the sun, a great quantity of excellent salt; this salt is thrown together in the Gabboul, or salt house; but by others (e) we are informed, that near about an hour's distance from the city of Tadmor, see Kg1 9:18 Ch2 8:3, is to be seen a large valley of salt, affording great quantities thereof; and it is thought that this is more probably the valley of salt mentioned here, than another which lies about four hours from Aleppo, and has sometimes passed for it; and which the above accounts show: but a modern writer (f), in his account of Palmyra, the same with Tadmor, speaks of a great plain, all covered with salt, from whence the whole country round is supplied. This plain is about a league from Palmyra, and extends itself towards the eastern part of Idumea (or Edom) the capital city of which was Bozra; and indeed this valley being both in Syria, and reaching to the borders of Edom, bids fair to be the valley here spoken of.

David gat him a name when he returned from smiting of the Syrians--Instead of Syrians, the Septuagint version reads "Edomites," which is the true reading, as is evident from Sa2 8:14. This conquest, made by the army of David, was due to the skilful generalship and gallantry of Abishai and Joab. (Ch1 18:12; compare Psa 60:1, title.) The valley was the ravine of salt (the Ghor), adjoining the Salt Mountain, at the southwestern extremity of the Dead Sea, separating the ancient territories of Judah and Edom [ROBINSON].
