Judges 3:2 DBY

¹  Now these are the nations which the LORD left, to test Israel by them, that is, all in Israel who had no experience of any war in Canaan;

²  it was only that the generations of the people of Israel might know war, that he might teach war to such at least as had not known it before.

³  These are the nations: the five lords of the Philistines, and all the Canaanites, and the Sido'nians, and the Hivites who dwelt on Mount Lebanon, from Mount Ba'al-her'mon as far as the entrance of Hamath.

⁴  They were for the testing of Israel, to know whether Israel would obey the commandments of the LORD, which he commanded their fathers by Moses.
