Judges 2:20-23

20So the anger of the Lord was kindled against Israel, and he said, "Because this people have transgressed my covenant that I commanded their fathers and have not obeyed my voice,

21I will no longer drive out before them any of the nations that Joshua left when he died,

22in order to test Israel by them, whether they will take care to walk in the way of the Lord as their fathers did, or not."

23So the Lord left those nations, not driving them out quickly, and he did not give them into the hand of Joshua.
