And Hadarezer sent,.... The same with Hadadezer, 2Sa 8:3, who was at the head of this confederacy, and to whom the rest of the kings of Syria were servants, 2Sa 10:19;and brought out the Syrians that [were] beyond the river; the river Phrat or Euphrates, as the Targum; so the Arabic version and Josephus , who says, that he hired them:and they came to Helam; which, according to the same writer, was king of the Syrians beyond Euphrates; but it seems to be the name of a place, where was the general rendezvous of the Syrian army.
Junius conjectures that it is the same with the Alamatha of Ptolemy , which he places with the Trachonite Arabs near the Euphrates:and Shobach the captain of the host of Hadarezer [went] before them: before the whole combined army, which according to Josephus , consisted of eighty thousand foot, and ten thousand horse: this general is called Shophach, 1Ch 19:16 the letters "B" and "P" being of the same pronunciation in the Hebrew tongue, as Kimchi observes, though it is there read "Shobach", in the Syriac and Arabic versions; he was no doubt a very able, valiant, and skilful general, since he is particularly mentioned by name, and whose name was then famous; the Arabic version calls him a spear bearer of Hadarezer.
