John Gill Commentary 2 Chronicles 11:10

"and Zorah, and Aijalon, and Hebron, which are in Judah and in Benjamin, fortified cities." — 2 Chronicles 11:10 (ASV)

And Zorah
The same with Zoreah, (Joshua 15:33) ,

and Aijalon ;
there was a city of the tribe of Dan of this name, in the valley of which the moon stood still in the times of Joshua, (Joshua 10:12) (19:42) , but whether the same with this, and now belonging to Judah, or another of the same name, is not certain:

and Hebron ;
a city in the mountainous part of Judah, and a city of refuge, about twenty miles from Jerusalem, (Joshua 15:54) (20:7) ,

which are in Judah and in Benjamin fenced cities ;
as they were now made by Rehoboam.
