(9) When Joab saw.--The keen eye of this experienced general at once took in both the advantages and the danger of this disposition of the enemy. He threw his whole force between their two divisions, organising his own army in two parts, one facing the Ammonites and the other the Syrians, but each capable of supporting the other in case of need. The enemy was thus cut in two, while the Israelites formed one compact body. He himself took command of the wing facing the Syrians with the choice troops of Israel, as having the stronger enemy to meet, while he gave the rest of the forces opposing the Ammonites into the hand of his brother Abishai.
Verse 9. - The front of the battle. The object of Joab was to prevent at all hazards the junction of the Syrians with the Ammonites, and he was only just in time to throw himself between them. This was resolute but dangerous policy, as, in case of defeat, he would have a powerful enemy in his rear. Apparently, however, he was aware that his real work lay with the Syrian mercenaries, who were dangerous enough by themselves, and would become more than a match for him if they were reinforced by the men of Rabbah. He therefore leaves Abishai with such troops as he could spare to watch the Ammonites, feeling sure that they would not hazard an attack unless they saw matters going ill with him; and, taking with him all his bravest men, "the choice man of Israel," he prepares with them to give battle to 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.
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.
