Judges 3:1

Now these [are] the nations which the Lord left to prove
Israel by them
Which are later mentioned, ( Judges 3:3 Judges 3:5 ) ;

[even] as many [of Israel] as had not known all the wars of Canaan;

Judges 3:1 In-Context

1 These are the nations the LORD left to test all those Israelites who had not experienced any of the wars in Canaan

2 (he did this only to teach warfare to the descendants of the Israelites who had not had previous battle experience):

3 the five rulers of the Philistines, all the Canaanites, the Sidonians, and the Hivites living in the Lebanon mountains from Mount Baal Hermon to Lebo Hamath.

4 They were left to test the Israelites to see whether they would obey the LORD’s commands, which he had given their ancestors through Moses.

5 The Israelites lived among the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites.
