Joshua 17:11-18

Also, in Issachar and in Asher, Manasseh had Beth-shean and its towns and Ibleam and its towns, and the inhabitants of Dor and its towns, and the inhabitants of En-dor and its towns, and the inhabitants of Taanach and its towns, and the inhabitants of Megiddo and its towns; the third is Napheth. But the sons of Manasseh were not able to [drive out the inhabitants and] take possession of these cities, because the Canaanites persisted in living in that land. When the Israelites became strong, they put the Canaanites to forced labor, but they did not drive them out completely. The sons of Joseph spoke to Joshua, saying, “Why have you given us only one lot and one portion as an inheritance, when we are a numerous people whom the LORD has so far blessed?” Then Joshua replied, “If you are a numerous people, go up to the forest and clear ground for yourselves there in the land of the Perizzites and the Rephaim, since the hill country of Ephraim is too narrow for you.” The sons of Joseph said, “The hill country is not enough for us, and all the Canaanites who live in the valley have iron chariots, both those who are in Beth-shean and its towns and those in the Valley of Jezreel.” Joshua said to the house of Joseph, to Ephraim and to Manasseh, “You are a numerous people and have great power; you shall not have only one lot, but the hill country shall be yours. For though it is a forest, you shall clear it and possess it to its farthest borders; for you shall drive out the Canaanites, even though they have iron chariots and though they are strong.”
