3. The third of his campaigns was against Hadadezer, the son of Rehob, king of Zobah. It is said in the chapter before us that the encounter with this prince took place "as he went to recover his border at the river Euphrates;" in the parallel passage of 1 Chronicles it is "as he went to establish his dominion by the river Euphrates." The natural interpretation is, that David was on his way to establish his dominion by the river Euphrates, when this Hadadezer came out to oppose him. The terms of the covenant of God with Abraham assigned to him the land "from the river of Egypt to the great river, the river Euphrates" (Gen. xv. 18), and when the territory was again defined to Joshua, its boundary was "from the wilderness and this Lebanon even unto the great river, the river Euphrates." Under the provisions of this covenant, as made by Him whose is the earth and the fulness thereof, David held himself entitled to fix the boundary of his dominion by the banks of the river. In what particular form he designed to do this, we are not informed; but whatever may have been his purpose, Hadadezer set himself to defeat it. The encounter with Hadadezer could not but have been serious to David, for his enemy had a great force of military chariots and horsemen against whom he could oppose no force of the same kind. Nevertheless, David's victory was complete; and in dealing with that very force in which he himself was utterly deficient, he was quite triumphant; for he took from his opponent a thousand and seven hundred horsemen, as well as twenty thousand footmen. There must have been some remarkable stroke of genius in this achievement, for nothing is more apt to embarrass and baffle a commonplace general than the presence of an opposing force to which his army affords no counterpart.
4. But though David had defeated Hadadezer, not far, as we suppose, from the base of Mount Hermon, his path to the Euphrates was by no means clear. Another body of Syrians, the Syrians of Damascus, having come from that city to help Hadadezer, seem to have been too late for this purpose, and to have encountered David alone. This, too, was a very serious enterprise for David; for though we are not informed whether, like Hadadezer, they had arms which the king of Israel could not match, it is certain that the army of so rich and civilized a state as Syria of Damascus would possess all the advantages that wealth and experience could bestow. But in his battle with them, David was again completely victorious. The slaughter was very great--two-and-twenty thousand men. This immense figure illustrates our remark a little while ago: that the slaughter of defeated and retreating armies was usually prodigious. So entire was the humiliation of this proud and ancient kingdom, that "the Syrians became servants to David, and brought presents," thus acknowledging his suzerainty over them. Between the precious things that were thus offered to King David and the spoil which he took from captured cities, he brought to Jerusalem an untold mass of wealth, which he afterwards dedicated for the building of the Temple.
5. In one case, the campaign was a peaceful one. "When Toi, king of Hamath, heard that David had smitten all the host of Hadadezer, then Toi sent Joram his son unto King David to salute him and to bless him, because he had fought against Hadadezer and had smitten him, for Hadadezer had wars with Toi." The kingdom of Toi lay in the valley between the two parallel ranges of Lebanon and anti-Lebanon, and it too was within the promised boundary, which extended to "the entering in of Hamath." Accordingly, the son of Toi brought with him vessels of silver, and vessels of gold, and vessels of brass; these also did King David dedicate to the Lord. The fame of David as a warrior was now such, at least in these northern regions, that further resistance seemed out of the question. Submission was the only course when the conqueror was evidently supported by the might of Heaven.
