So Joram went over to Zair
 A city in Edom, the same with the Zaara of Ptolemy F9; 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.
