John Gill Commentary Joshua 15:39

"Lachish, and Bozkath, and Eglon," — Joshua 15:39 (ASV)

Lachish
Lachish and Eglon were royal cities, of which see (Joshua 10:3) ;

and Bozkath ,
is called Boscath, of which place was the mother of King Josiah, (2 Kings 21:1) ; some take it to be the same with Bascana, as in the Apocrypha:

``And when he came near to Bascama he slew Jonathan, who was buried there.''

and Eglon
also was a royal city, of which see (Joshua 10:3) .
