stronger force of the two. He then made this arrangement with Abishai (2Sa 10:11): “If Aram becomes stronger than I (i.e., overpowers me), come to my help; and if the Ammonites should overpower thee, I will go to help thee.” Consequently the attack was not to be made upon both the armies of the enemy simultaneously; but Joab proposed to attack the Aramaeans (Syrians) first (cf. 2Sa 10:13), and Abishai was merely to keep the Ammonites in check, though there was still a possibility that the two bodies of the enemy might make their attack simultaneously.
Verse 12
2Sa 10:12“Be firm, and let us be firm (strong) for our people, and for the towns of our God: and Jehovah will do what seemeth Him good.” Joab calls the towns of Israel the towns of our God, inasmuch as the God of Israel had given the land to the people of Israel, as being His own property. Joab and Abishai were about to fight, in order that Jehovah's possessions might not fall into the hands of the heathen, and become subject to their gods.
Verses 13-14
Joab then advanced with his army to battle against Aram, and “they fled before him.” - 2Sa 10:14. When the Ammonites perceived this, they also fled before Abishai, and drew back into the city (Rabbah); whereupon Joab returned to Jerusalem, probably because as we may infer from 2Sa 11:1, it was too late in the year for the siege and capture of Rabbah.
Verses 15-16
The Aramaeans, however, gathered together again after the first defeat, to continue the war; and Hadarezer, the most powerful of the Aramaean kings, sent messengers to Mesopotamia, and summoned it to war. It is very evident, not only from the words “he sent and brought out Aram, which was beyond the river,” but also from the fact that Shobach, Hadarezer's general (Shophach according to the Chronicles), was at the head of the Mesopotamian troops, that the Mesopotamian troops who were summoned to help were under the supreme ruler of Hadarezer. This is placed beyond all possible doubt by 2Sa 10:19, where the kings who had fought with Hadarezer against the Israelites are called his “servants,” or vassals. חילם ויּבאוּ (2Sa 10:16) might be translated “and their army came;” but when we compare with this the חלאמה ויּבא of 2Sa 10:17, we are compelled to render it as a proper name (as in the Septuagint, Chaldee, Syriac, and Arabic) - “and they (the men from beyond the Euphrates) came (marched) to Helam” - and to take חילם
