8 The children of Ammon came out, and put the battle in array at the entrance of the gate: and the Syrians of Zobah and of Rehob, and the men of Tob and Maacah, were by themselves in the field.
*Minor differences ignored. Grouped by changes, with first version listed as example.
Came out - From their city, Rabbah Deuteronomy 3:11, Deuteronomy 3:15 or 20 miles from Medeba, where 1-Chronicles 19:7 the Syrian army was encamped. Medeba (modern Madeba) was taken from Sihon Numbers 21:30, and fell to Reuben Joshua 13:9, Joshua 13:16; in the reign of Ahaz it seems to have returned to Moab Isaiah 15:2, and in the time of the Maccabees to the Amorites (1 Macc. 9:36, 37). In church history it was a bishop's see.
In the field - i. e. in the plain below the round rocky hill on which the city stood.
At the entering in of the gate - This was the city of Medeba, as we learn from 1-Chronicles 19:7.
And the children of Ammon came out, and put the battle in array at the entering in of the gate: and the Syrians of (d) Zoba, and of Rehob, and Ishtob, and Maacah, [were] by themselves in the field.
(d) These were various parts of the country of Syria, by which it appears that the Syrians served where they might have entertainment, as now the Sweitzers do.
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.
(u) Antiqu. l. 7. c. 6. sect. 2.
On the other hand, the Ammonites came out (from the capital, where they had assembled), and put themselves in battle array before the gate. The Syrians were alone on the field, i.e., they had taken up a separate position on the broad treeless table-land (cf. Joshua 13:16) by Medeba. Medeba lay about four geographical miles in a straight line to the south-west of Rabbath-Ammon.
