Judges 3:2-4

2He wanted to teach the young men of Israel how to fight their enemies, because they had not fought battles before.

3The nations who remained were: the Philistines, with their five kings, all the Canaanites, the Sidonians, the Hivites who lived in the Lebanon mountains, from Mount Baal Hermon to Lebo-Hamath.

4These nations were still there to test the Israelites. The Lord wanted to know if his people would obey his commands. Those were the commands that he had told Moses to give to the ancestors of the Israelites.
