'Managed' in the Bible

The men of Manasseh did not conquer Beth Shan, Taanach, or their surrounding towns. Nor did they conquer the people living in Dor, Ibleam, Megiddo or their surrounding towns. The Canaanites managed to remain in those areas.

The Amorites managed to remain in Har Heres, Aijalon, and Shaalbim. Whenever the tribe of Joseph was strong militarily, the Amorites were forced to do hard labor.
