Judges 3:4-8

They were for the testing of Israel, to know whether Israel would obey the commandments of the LORD, which he commanded their fathers by the hand of Moses. So the people of Israel lived among the Canaanites, the Hittites, the Amorites, the Perizzites, the Hivites, and the Jebusites. And their daughters they took to themselves for wives, and their own daughters they gave to their sons, and they served their gods. And the people of Israel did what was evil in the sight of the LORD. They forgot the LORD their God and served the Baals and the Asheroth. Therefore the anger of the LORD was kindled against Israel, and he sold them into the hand of Cushan-rishathaim king of Mesopotamia. And the people of Israel served Cushan-rishathaim eight years.
