15:36 cities with their villages. The cities were walled, with smaller villages around them, with each such complex comprising a city-state governed by a “king.”
15:63 inhabitants of Jerusalem. Joshua had defeated “the king of Jerusalem” (Joshua 12:7, 10), but apparently did not destroy the Jebusites.

15:63 drive them out. Jerusalem was actually in the territory assigned to the tribe of Benjamin (Judah was the southernmost tribe, with Benjamin just north of Judah). However, it was close to Judah’s border, and eventually David, of the tribe of Judah, was able to drive out the Jebusites (II Samuel 5:6-9), and then make it his capital.
