The two armies of the Ammonites and the Syrians were drawn up facing one another; the Ammonites supported by the city Rabbah behind them; the Syrians in great force, with numerous chariots able to manoeuvre in the plain in front of Medeba. If Joab advanced against either, he would have the other in his rear.

Before and behind - It is probable that one of the armies was in the field, and the other in the city, when Joab arrived. When he fronted this army, the other appears to have issued from the city, and to have taken him in the rear; he was therefore obliged to divide his army as here mentioned; one part to face the Syrians commanded by himself, and the other to face the Ammonites commanded by his brother Abishai.

When Joab saw that the front of the battle was against him before and behind,.... Or "the face" of it (w); armies appeared both before and behind, about to attack him both in front and rear; the Targum is,"and Joab saw that the warriors, or those that made war, were strong against him before and behind:"

he chose of all the choice men of Israel; the most eminent for strength, and valour, and military skill, who had been tried, and were famous for warlike exploits, the flower of the army:

and put them in array against the Syrians; who might be the strongest party, and the best soldiers; though being but mercenaries, if hard beset, would sooner give way, as he might suppose, upon which the Ammonites would do the same.

When Joab saw that "the front of the war was (directed) against him both before and behind," he selected a picked body out of the Israelitish army, and posted them (the picked men) against the children of Aram (i.e., the Syrians). The rest of the men he gave to his brother Abishai, and stationed them against the Ammonites. "The front of the battle:" i.e., the face or front of the hostile army, when placed in battle array. Joab had this in front and behind, as the Ammonites had taken their stand before Rabbah at the back of the Israelitish army, and the Syrians by Medeba in their front, so that Joab was attacked both before and behind. This compelled him to divide his army. He chose out, i.e., made a selection. Instead of בישׂראל בּחוּרי (the picked men in Israel) the Chronicles have בישׂראל בּחוּר (the men in Israel), the singular בּחוּר being more commonly employed than the plural to denote the men of war. The בּ before ישׂראל is not to be regarded as suspicious, although the early translators have not expressed it, and the Masoretes wanted to expunge it. "The choice of Israel" signifies those who were selected in Israel for the war, i.e., the Israelitish soldiers. Joab himself took up his station opposite to the Syrians with a picked body of men, because they were the stronger force of the two. He then made this arrangement with Abishai (2 Samuel 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. 2 Samuel 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.

When Joab saw that the front of the battle was against him before and behind, he chose of all the choice men of Israel, and put them in array against the Syrians:

10:6-14 They that are at war with the Son of David, not only give the provocation, but begin the war. God has forces to send against those that set his wrath at defiance, Isa 5:19, which will convince them that none ever hardened his heart against God, and prospered. Christ's soldiers should strengthen one another's hands in their spiritual warfare. Let nothing be wanting in us, whatever the success be. When we make conscience of doing our duty, we may, with satisfaction, leave the event with God, assuredly hoping for his salvation in his own way and time.
