1 Chronicles 5:8

And Bela the son of Azaz, the son of Shema, the son of Joel,
&c.] 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).
