Albert Barnes Commentary 2 Chronicles 13:19

"And Abijah pursued after Jeroboam, and took cities from him, Beth-el with the towns thereof, and Jeshanah with the towns thereof, and Ephron with the towns thereof." — 2 Chronicles 13:19 (ASV)

Jeshanah is probably identical with the “Isanas” of Josephus, where a battle took place in the war between Antigonus and Herod; however, its location cannot be determined. For Ephraim, see the note on Joshua 18:23.
