Judges 2:20-23

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