Judges 2:20-Judges 3:4 - The Lord Allows The Nations To Stay In Order To Test His People
20 The Lord was furious with Israel. He said, "This nation has violated the terms of the agreement I made with their ancestors by disobeying me. 21 So I will no longer remove before them any of the nations that Joshua left unconquered when he died. 22 Joshua left those nations to test Israel. I wanted to see whether or not the people would carefully walk in the path marked out by the Lord, as their ancestors were careful to do." 23 This is why the Lord permitted these nations to remain and did not conquer them immediately; he did not hand them over to Joshua.
1 These were the nations the Lord permitted to remain so he could use them to test Israel -- he wanted to test all those who had not experienced battle against the Canaanites. 2 He left those nations simply because he wanted to teach the subsequent generations of Israelites, who had not experienced the earlier battles, how to conduct holy war. 3 These were the nations: the five lords of the Philistines, all the Canaanites, the Sidonians, and the Hivites living in Mount Lebanon, from Mount Baal Hermon to Lebo-Hamath. 4 They were left to test Israel, so the Lord would know if his people would obey the commands he gave their ancestors through Moses.
