But their allies the Syrians were not disposed to yield without another conflict. Determined to do his utmost, Hadarezer, king of the Syrians of Zobah, sent across the Euphrates, and prevailed on their neighbours there to join them in the effort to crush the power of David. That a very large number of these Mesopotamian Syrians responded to the invitation of Hadarezer is apparent from the number of the slain (ver. 18). The matter assumed so serious an aspect that David himself was now constrained to take the field, at the head of "all Israel." The Syrian troops were commanded by Shobach, who appears to have been a distinguished general. It must have been a death-struggle between the Syrian power and the power of David. But again the victory was with the Israelites, and among the slain were the men of seven hundred chariots, and forty thousand horsemen (1 Chron. xix. 18, "footmen"), along with Shobach, captain of the Syrian host. It must have been a most decisive victory, for after it took place all the states that had been tributary to Hadarezer transferred their allegiance to David. The Syrian power was completely broken; all help was withdrawn from the Ammonites, who were now left to bear the brunt of their quarrel alone. Single-handed, they had to look for the onset of the army which had so remarkably prevailed against all the power of Syria, and to answer to King David for the outrage they had perpetrated on his ambassadors. Very different must their feelings have been now from the time when they began to negotiate with Syria, and when, doubtless, they looked forward so confidently to the coming defeat and humiliation of King David.
