'Nations' in the Bible

I also will no longer drive out before them any of the nations which Joshua left when he died,

These nations are: the five lords of the Philistines and all the Canaanites and the Sidonians and the Hivites who lived in Mount Lebanon, from Mount Baal-hermon as far as Lebo-hamath.
