Charles Ellicott Commentary 1 Chronicles 1:44-45

"And Bela died, and Jobab the son of Zerah of Bozrah reigned in his stead. And Jobab died, and Husham of the land of the Temanites reigned in his stead." — 1 Chronicles 1:44-45 (ASV)

(44, 45) Bozrah. —“Portress” (the Byrsa of Carthage); was one of the capitals of Edom, perhaps identical with Mibzar (fortress, 1 Chronicles 1:53). Eusebius mentions Mabsara as a large town in Gebalene. It is now represented by the ruins of Al-Bussireh in Jebal. See Amos 1:12, I will send a fire upon Teman, which shall devour the palaces of Bozrah; and Isaiah 34:6.
