4 Nations the Lord left to test Israel in the days of the Judges

Judges 3:1-3

These are the nations the Lord left to test all those Israelites who had not experienced any of the wars in Canaan (he did this only to teach warfare to the descendants of the Israelites who had not had previous battle experience):

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.
