Judges 2:21-23

American Standard Version

²¹ I also will not henceforth drive out any from before them of the nations that Joshua left when he died; ²² that 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. ²³ So Jehovah left those nations, without driving them out hastily; neither delivered he them into the hand of Joshua.
