Who dwelt in Aroer - This town was situated on the river Arnon; and Nebo was both a city and a mountain in the same country. They both lay on the other side of Jordan.
And Bela the son of Azaz, the son of Shema, the son of Joel, who dwelt in (d) Aroer, even unto Nebo and Baalmeon:
(d) These places were beyond Jordan toward the east in the land given to the Reubenites.
And Bela the son of Azaz, the son of Shema, the son of Joel,.... The pedigree of Bela, another principal man in the tribe of Reuben, is traced up to Joel the father of Shema; the same with Shemaiah, according to Kimchi and Ben Melech, 1-Chronicles 5:4
who dwelt in Aroer; which belonged to the tribe of Gad, and was rebuilt by them, Numbers 32:34 wherefore Kimchi observes, it may be interpreted, either from Aroer, or on the border of it, Bela dwelt:
even unto Nebo, and Baalmeon; of which See Gill on Numbers 32:38.
