20. So the anger of the Lord was kindled against Israel; and He said, Because this people have transgressed My covenant which I commanded their fathers and have not listened to My voice,
21. I from now on will also not drive out from before them any of the nations which Joshua left when he died,
22. That through them I may prove Israel, whether they will keep the way of the Lord to walk in it, as their fathers kept it, or not.
23. So the Lord left those nations, without driving them out at once, nor had He delivered them into Joshua's power.
