Judges 3:4-8

And they were left, to prove Israel by them, to know whether they would hearken unto the commandments of Jehovah, which he commanded their fathers by Moses. And the children of Israel dwelt among the Canaanites, the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites: and they took their daughters to be their wives, and gave their own daughters to their sons and served their gods. And the children of Israel did that which was evil in the sight of Jehovah, and forgat Jehovah their God, and served the Baalim and the Asheroth. Therefore the anger of Jehovah was kindled against Israel, and he sold them into the hand of Cushan-rishathaim king of Mesopotamia: and the children of Israel served Cushan-rishathaim eight years.
