God had given David rest from all his enemies that opposed him and made head against him; and he having made a good use of that rest, has now commission given him to make war upon them, and to act offensively for the avenging of Israel's quarrels and the recovery of their rights; for as yet they were not in full possession of that country to which by the promise of God they were entitled.

I.He quite subdued the Philistines, Sa2 8:1. They had attacked him when they thought him weak (Sa2 5:17), and went by the worst then; but, when he found himself strong, he attacked them, and made himself master of their country. They had long been vexatious and oppressive to Israel. Saul got no ground against them; but David completed Israel's deliverance out of their hands, which Samson had begun long before, Jdg 13:5. Metheg-ammah was Gath (the chief and royal city of the Philistines) and the towns belonging to it, among which there was a constant garrison kept by the Philistines on the hill Ammah (Sa2 2:24), which was Metheg, a bridle (so it signifies) or curb upon the people of Israel; this David took out of their hand and used it as a curb upon them. Thus, when the strong man is disarmed, the armour wherein he trusted is taken from him, and used against him, Luk 11:22. And after the long and frequent struggles which the saints have had with the powers of darkness, like Israel with the Philistines, the Son of David shall tread them all under their feet and make the saints more than conquerors.

II.He smote the Moabites, and made them tributaries to Israel, Sa2 8:2. He divided the country into three parts, two of which he destroyed, casting down the strong-holds, and putting all to the sword; the third part he spared, to till the ground and be servants to Israel. Dr. Lightfoot says, "He laid them on the ground and measured them with a cord, who should be slain and who should live;" and this is called meting out the valley of Succoth, Psa 60:6. The Jews say he used this severity with the Moabites because they had slain his parents and brethren, whom he put under the protection of the king of Moab during his exile, Sa1 22:3, Sa1 22:4. He did it in justice, because they had been dangerous enemies to the Israel of God; and in policy, because, if left in their strength, they still would have been so. But observe, Though it was necessary that two-thirds should be cut off, yet the line that was to keep alive, though it was but one, is ordered to be a full line. Be sure to give that length enough; let the line of mercy be stretched to the utmost in favorem vitae - so as to favour life. Acts of indemnity must be construed so as to enlarge the favour. Now Balaam's prophecy was fulfilled, A sceptre shall arise out of Israel, and shall smite the corners of Moab, to the utmost of which the fatal line extended, Num 24:17. The Moabites continued tributaries to Israel till after the death of Ahab, Kg2 3:4, Kg2 3:5. Then they rebelled and were never reduced.

III.He smote the Syrians or Aramites. Of them there were two distinct kingdoms, as we find them spoken of in the title of the 60th Psalm: Aram Naharaim, - Syria of the rivers, whose head city was Damascus (famed for its rivers, Kg2 5:12), and Aram Zobah, which joined to it, but extended to Euphrates. These were the two northern crowns. 1. David began with the Syrians of Zobah, Sa2 8:3, Sa2 8:4. As he went to settle his border at the river Euphrates (for so far the land conveyed by the divine grant to Abraham and his seed did extend, Gen 15:18), the king of Zobah opposed him, being himself possessed of those countries which belonged to Israel; but David routed his forces, and took his chariots and horsemen. The horsemen are here said to be 700, but Ch1 18:4 they are said to be 7000. If they divided their horse by ten in a company, as it is probable they did, the captains and companies were 700, but the horsemen were 7000. David houghed the horses, cut the sinews of their hams, and so lamed them, and made them unserviceable, at least in war, God having forbidden them to multiply horses, Deu 17:16. David reserved only 100 chariots out of 1000 for his own use: for he placed his strength not in chariots nor horses, but in the living God (Psa 20:7), and wrote it from his own observation that a horse is a vain thing for safety, Psa 33:16, Psa 33:17. 2. The Syrians of Damascus coming in to the relief of the king of Zobah fell with him. 22,000 were slain in the field, Sa2 8:5. So that it was easy for David to make himself master of the country, and garrison it for himself, Sa2 8:6. The enemies of God's church, that think to secure themselves, will prove, in the end, to ruin themselves, by their confederacies with each other. Associate yourselves, and you shall be broken in pieces, Isa 8:9.

IV.In all these wars, 1. David was protected: The Lord preserved him whithersoever he went. It seems, he went in person, and, in the cause of God and Israel, jeoparded his own life in the high places of the field; but God covered his head in the day of battle, which he often speaks of, in his psalms, to the glory of God. 2. He was enriched. He took the shields of gold which the servants of Hadadezer had in their custody (Sa2 8:7) and much brass from several cities of Syria (Sa2 8:8), which he was entitled to, not only jure belli - by the uncontrollable right of the longest sword ("Get it, and take it"); but by commission from heaven, and the ancient entail of these countries on the seed of Abraham.

David smote - Hadadezer - He is supposed to have been king of all Syria, except Phoenicia; and, wishing to extend his dominions to the Euphrates, invaded a part of David's dominions which lay contiguous to it; but being attacked by David, he was totally routed.

And David also smote Hadadezer the son of Rehob, king of Zobah,.... Called sometimes Aramzobah, and was a part of Syria, as its name shows. Benjamin, of Tudela (h) takes it to be the same with Haleb or Aleppo; Josephus (i) calls it Sophene; but that is placed by Ptolemy (k) beyond the Euphrates; whereas this country must be between that river and the land of Israel, and was contiguous to it, and near Damascus; and it was so near the land of Israel, and being conquered by David, that it became a controversy with the Jews, whether it was not to be reckoned part of it, and in several things they allow it to be equal to it (l). Rehob was the first king of this part of Syria, and then his son the second and last; he is called Hadarezer in Ch1 18:3; the letters "D" and "R", being frequently changed in the Hebrew tongue: him David fought with, and overcame:

as he went to recover his border at the river Euphrates; which some understand of Hadadezer, so Jarchi and Kimchi, who attempted to recover part of his dominions that had been taken by some one or another from him, which lay upon the river Euphrates; or he endeavoured to enlarge his dominions, and carry them as far as the river, and establish the borders of them; and while he was doing this, or attempting it, David fell upon him, and routed him; or rather this refers to David, who considering that the ancient border of the land of Israel, as given to Abraham, reached to the river Euphrates, Gen 15:18; he set out on an expedition to recover this border, and whereas the country of this king lay in his way, he invaded that; upon which Hadadezer rose up against him, and was conquered by him, and by this means the border was recovered to the kingdom of Israel, and reached so far, as is plain it did in Solomon's time, Kg1 4:21.

HE SMITES HADADEZER AND THE SYRIANS. (Sa2 8:3-14)

Zobah-- (Ch1 18:3). This kingdom was bounded on the east by the Euphrates, and it extended westward from that river, perhaps as far north as Aleppo. It was long the chief among the petty kingdoms of Syria, and its king bore the hereditary title of "Hadadezer" or "Hadarezer" ("Hadad," that is, "helped").

as he went to recover his border at the river Euphrates--in accordance with the promises God made to Israel that He would give them all the country as far as the Euphrates (Gen 15:18; Num 24:17). In the first campaign David signally defeated Hadadezer. Besides a great number of foot prisoners, he took from him an immense amount of booty in chariots and horses. Reserving only a small number of the latter, he hamstrung the rest. The horses were thus mutilated because they were forbidden to the Hebrews, both in war and agriculture. So it was of no use to keep them. Besides, their neighbors placed much dependence on cavalry, but having, for want of a native breed, to procure them by purchase, the greatest damage that could be done to such enemies was to render their horses unserviceable in war. (See also Gen 46:6; Jos 11:6, Jos 11:9). A king of Damascene-Syria came to Hadadezer's succor; but David routed those auxiliary forces also, took possession of their country, put garrisons into their fortified towns, and made them tributary.
