Albert Barnes Commentary 2 Chronicles 11:9-10

"and Adoraim, and Lachish, and Azekah, and Zorah, and Aijalon, and Hebron, which are in Judah and in Benjamin, fortified cities." — 2 Chronicles 11:9-10 (ASV)

The location of Adoraim is uncertain. For the locations of the other cities, see the following: Lachish in Joshua 10:3; Azekah in Joshua 10:10; Zorah in Joshua 15:33; Aijalon in Joshua 10:12; and Hebron in Joshua 14:15. None of these cities were actually within the territory of the tribe of Benjamin. The writer uses the phrase “Judah and Benjamin” simply as the common designation for the southern kingdom (compare 2 Chronicles 11:12 and 2 Chronicles 11:23).
