(8) At the entering in of the gate.--The Ammonites and their allies formed separate armies, the former taking their stand immediately before the city, the latter "by themselves" at some distance, where the ground was more favourable for the man?uvres of their chariots.
Verse 8. - The Syrians... were by themselves in the field. We learn from 1 Chronicles 19:7 that the rendezvous of the Arameans was at Medeba, a small town situated upon a hill in the Mishor, or treeless prairie land, called "the plain" in Joshua 13:16. As it was four miles southeast of Heshbon, and more than twenty miles distant from Rabbah, it is plain that they were marching northward, and that Joab was only just in time to prevent a junction of the two armies. The Ammonites, who were expecting their allies, and knew of their approach, had come outside of Rabbah, but had only posted themselves in fighting order "at the entering in of the gate."
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.
And the children of Ammon came out,.... Either out of Rabbah their metropolis, as Josephus (u); or rather out of Medeba, as it seems from 1 Chronicles 19:7; a city that lay on the borders of their country, and was a frontier town, see Numbers 21:30;
and put the battle in array, at the entering in of the gate; of the city of Medeba; they were first within the city, but, upon the approach of Joab and his army, they came out and drew up in a line of battle at the gate of it:
and the Syrians of Zoba, and of Rehob, and Ishtob, and Maacah, were by themselves in the field; at some distance from the city, the Ammonites not choosing to trust: mercenaries in it; and perhaps they placed these ambush in the field, to get Joab between two fires, as we now express it.
