Judges 2:20-23

20And the anger of Jehovah was hot against Israel; and he said, Because this nation hath transgressed my covenant which I commanded their fathers, and hath not hearkened unto my voice, 21I also will not henceforth dispossess from before them any of the nations that Joshua left when he died; 22that through them I may prove Israel, whether they will keep the way of Jehovah to walk therein, as their fathers did keep [it], or not. 23Therefore Jehovah left those nations, without dispossessing them hastily, neither delivered he them into the hand of Joshua.
