John Gill Commentary 1 Chronicles 8:13

"and Beriah, and Shema, who were heads of fathers` [houses] of the inhabitants of Aijalon, who put to flight the inhabitants of Gath;" — 1 Chronicles 8:13 (ASV)

Beriah also, and Shema
These were sons of Elpaal:

who were heads of the fathers of the inhabitants of Aijalon ;
which, though in the tribe of Dan, (Joshua 19:42) might afterwards come into the possession of Benjamin; or this may be another place of the same name in Benjamin; or, however, might be inhabited by Benjaminites, upon the return from captivity, who descended from those men:

who drove away the inhabitants of Gath ;
dispossessed them of their city, in revenge for what they had done to the Ephraimites, (1 Chronicles 7:21) .
