Judges 3:2-4

Young's Literal Translation

² (only for the sake of the generations of the sons of Israel's knowing, to teach them war, only those who formerly have not known them) --

³ five princes of the Philistines, and all the Canaanite, and the Zidonian, and the Hivite inhabiting mount Lebanon, from mount Baal-Hermon unto the entering in of Hamath;

⁴ and they are to prove Israel by them, to know whether they obey the commands of Jehovah that He commanded their fathers by the hand of Moses.
