2:21I also will not henceforth drive out any from before them of the nations which Joshua left when he died:

2:22That through them I may prove Israel, whether they will keep the way of the LORD to walk therein, as their fathers did keep it, or not.

3:1Now these are the nations which the LORD left, to prove Israel by them, even as many of Israel as had not known all the wars of Canaan;

3:2Only that the generations of the children of Israel might know, to teach them war, at the least such as before knew nothing thereof;

3:3Namely, five lords of the Philistines, and all the Canaanites, and the Sidonians, and the Hivites that dwelt in mount Lebanon, from mount Baalhermon unto the entering in of Hamath.

3:4And they were to prove Israel by them, to know whether they would hearken unto the commandments of the LORD, which he commanded their fathers by the hand of Moses.
