John Gill Commentary Joshua 15:60

"Kiriath-baal (the same is Kiriath-jearim), and Rabbah; two cities with their villages." — Joshua 15:60 (ASV)

Kirjathbaal, (which [is] Kirjathjearim,)
Of Kirjathbaal, and its several names, (See Gill on Joshua 15:9);

and Rabbah ,
of which we nowhere else read; for this is a very different city from the Rabbah of the children of Ammon, (2 Samuel 12:26) ;

two cities with their villages ;
why these are reckoned by themselves is not certain.
