John Gill Commentary Joshua 21:22

"and Kibzaim with its suburbs, and Beth-horon with its suburbs; four cities." — Joshua 21:22 (ASV)

And Kibzaim with her suburbs Which seems to, be the same with Jokneam, (1 Chronicles 6:68) ; of it we read nowhere else;

and Bethhoron with her suburbs ; upper Bethhoron, for there were two, an upper and a nether: see (Joshua 16:3Joshua 16:5) ;

four cities ; as mentioned by name.
