18 And when the Lord raised them up judges, then the Lord was with the judge, and delivered them out of the hand of their enemies all the days of the judge; for the Lord hearkened because of their groanings by reason of them that oppressed them and vexed them.
19 And it came to pass, when the judge was dead, that they returned, and corrupted themselves more than their fathers, in following other gods to serve them, and to bow down unto them; they ceased not from their own doings, nor from their stubborn way.
20 And the anger of the Lord was hot against Israel; and he said, Because that this people hath transgressed my covenant which I commanded their fathers, and have not hearkened unto my voice;
21 I also will not henceforth drive out any from before them of the nations which Joshua left when he died;
22 That 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.
23 Therefore the Lord left those nations, without driving them out hastily; neither delivered he them into the hand of Joshua.
Judges 3 Intro: The nations which were left to prove Israel -- By communion with them they commit idolatry.
1 Now 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;
2 Only that the generations of the children of Israel might know to teach them war, at the least such as before knew nothing thereof;
3 Namely, five lords of the Philistines, and all the Canaanites, and the Sidonians, and the Hivites that dwelt in mount Lebanon, from mount Baal-hermon unto the entering in of Hamath.
4 And 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.
