Judges 3:2-4

Wycliffe Bible

² and that afterward the sons of them should learn to fight with enemies, and to have custom of battle. (and so that through them their sons would learn to fight with their enemies, and know the ways of battle.)

³ He left (alive the) five princes of the Philistines, and all Canaanites, and the people of Sidon, and Hivites that dwelled in the hill Lebanon, from the hill Baalhermon till to the entering of Hamath. (He left alive the five rulers of the Philistines, and all the Canaanites, and the people of Sidon, and the Hivites who lived on Mount Lebanon, from Mount Baalhermon unto Hamath Pass.)

⁴ And he left them, that in them he should assay Israel, (to see) whether they would hear the behests of the Lord, which he commanded to their fathers by the hand of Moses, either nay. (Yea, he left them alive, so that through them he could test Israel, to see whether they would listen to the Lord’s commands, which he commanded to their fathers through Moses, or not.)
