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.
5 And the children of Israel dwelt among the Canaanites, Hittites, and Amorites, and Perizzites, and Hivites, and Jebusites;
6 And they took their daughters to be their wives, and gave their daughters to their sons, and served their gods.
7 And the children of Israel did evil in the sight of the Lord, and forgat the Lord their God and served Baalim and the groves.
8 Therefore the anger of the Lord was hot against Israel, and he sold them into the hand of Chushan-rishathaim king of Mesopotamia; and the children of Israel served Chushan-rishathaim eight years.
9 And when the children of Israel cried unto the Lord, the Lord raised up a deliverer to the children of Israel, who delivered them, even Othniel the son of Kenaz, Caleb's younger brother.
