Judges 1:28 When Israel became strong, they pressed the Canaanites into forced labour but never drove them out completely.

Judges 3:1 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 forefathers through Moses.
