21 Then Joram passed over to Zair, and all his chariots with him: and he rose up by night, and struck the Edomites who surrounded him, and the captains of the chariots; and the people fled to their tents.
*Minor differences ignored. Grouped by changes, with first version listed as example.
Zair - Perhaps Seir, the famous mountain of Edom Genesis 14:6.
The people - i. e., The Edomites. Yet, notwithstanding his success, Joram was forced to withdraw from the country, and to leave the natives to enjoy that independence 2-Kings 8:22, which continued until the time of John Hyrcanus, who once more reduced them.
Joram went over to Zair - This is the same as Seir, a chief city of Idumea. So Isaiah 21:11 : The burden of Dumah (Idumea). He calleth to me out of Seir.
Smote the Edomites - It appears that the Israelites were surrounded by the Idumeans; and that in the night Joram and his men cut their way through them, and so got every man to his tent, for they were not able to make any farther head against these enemies; and therefore it is said, that Edom revolted from under the hand of Judah unto this day.
So Joram went over to Zair,.... A city in Edom, the same with the Zaara of Ptolemy (i); some take it to be the same with Seir, the mountain or country of that name:
and all the chariots with him; all the chariots of war he had:
and he rose by night, and smote the Edomites which compassed him about; who came out of their cities in great numbers, and surrounded him, he having entered into their country in an hostile way, to subdue them:
and the captains of the chariots: which belonged to the Edomites; those he smote, 2-Chronicles 21:9.
and the people fled into their tents; the army being routed.
