Ezra
1 Chronicles 1:44ESV·traditional attribution

Bela died, and Jobab the son of Zerah of Bozrah reigned in his place.

Matthew Henry Presbyterian @wholebiblehenry

All nations but the seed of Abraham are already shaken off from this genealogy: they have no part nor lot in this matter. The Lord's portion is his people. Of them he keeps an account, knows them by name; but those who are strangers to him he beholds afar off.

Commenting on 1 Chronicles 1:28-54

Geneva Bible Notes Reformed @genevanotes

And when Bela was dead, Jobab the son of Zerah of Bozrah reigned in his stead. (n) Which was the principal city of the Edomites.

Adam Clarke Methodist @methodicalclarke

Bela was dead - "Being killed by Phineas, in the wilderness." - T. Jobab the son of Zerah - Supposed by some to be the same as Job, whose book forms a part of the canon of Scripture. But in their names there is no similarity; Job being written איוב aiyob; Jobab, יובב yobab. See the notes on Job, and the parallel place in Genesis.
