Judges 3:1-3

Now these are the nations which Jehovah left, to prove Israel by them, even as many of Israel as had not known all the wars of Canaan; only that the generations of the children of Israel might know, to teach them war, at the least such as beforetime knew nothing thereof: namely, the five lords of the Philistines, and all the Canaanites, and the Sidonians, and the Hivites that dwelt in mount Lebanon, from mount Baal-hermon unto the entrance of Hamath.
