Judges 3:4-8

And they were left, that He might test Israel by them, to know whether they would obey the commandments of the LORD, which He had commanded their fathers by the hand of Moses. Thus the children of Israel dwelt among the Canaanites, the Hittites, the Amorites, the Perizzites, the Hivites, and the Jebusites. And they took their daughters to be their wives, and gave their daughters to their sons; and they served their gods. So the children of Israel did evil in the sight of the LORD. They forgot the LORD their God, and served the Baals and Asherahs. Therefore the anger of the LORD was hot 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.
