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.
