Albert Barnes Commentary Joshua 11:17

"from mount Halak, that goeth up to Seir, even unto Baal-gad in the valley of Lebanon under mount Hermon: and all their kings he took, and smote them, and put them to death." — Joshua 11:17 (ASV)

The mount Halak - See the margin and reference. The name serves to mark the southern limit of Joshua’s conquests. It suits equally well several of the ranges near the south border of Palestine, and it is uncertain which of them is the one here indicated.

Baal-gad (Joshua 12:7; Joshua 13:5) is probably Paneas, the Caesarea Philippi of later times. The name means “troop or city of Baal,” or a place where Baal was worshipped as the giver of “good luck.” Compare Isaiah 65:11. It was probably the same as Baal-Hermon (Judges 3:3; 1 Chronicles 5:23).
