John Wesley on Joshua 15:8

Went up - Properly; for the line went from Jordan and the salt sea, to the higher grounds nigh Jerusalem; and therefore the line is said to go down, chap.18:16, because there it takes a contrary course, and goes downward to Jordan and the sea. Valley of Hinnom - A very pleasant place, but afterward made infamous. Of the Jebusites - Of the city of the Jebusites, which was anciently called Jebussi. Jerusalem - It may seem hence, that Jerusalem properly, or at least principally, belonged to Benjamin; and yet it is ascribed to Judah also; either because a part of the city was allotted to Judah; or because the Benjamites desired the help and conjunction of this powerful tribe of Judah, for the getting and keeping of this most important place. And when the Benjamites had in vain attempted to drive out the Jebusites, this work was at last done by the tribe of Judah, who therefore had an interest in it by the right of war; as Ziglag which belonged to the tribe of Simeon, being gotten from the Philistines by David, was joined by him to his tribe of Judah, 1Sam 27:6.
