Thematic Bible: A range of low mountains

And Joshua said unto them, If thou be a great people, get thee up to the forest, and cut down for thyself there in the land of the Perizzites and of the Rephaim; since the hill-country of Ephraim is too narrow for thee. And the children of Joseph said, The hill-country is not enough for us: and all the Canaanites that dwell in the land of the valley have chariots of iron, both they who are in Beth-shean and its towns, and they who are in the valley of Jezreel. And Joshua spake unto the house of Joseph, even to Ephraim and to Manasseh, saying, Thou art a great people, and hast great power; thou shalt not have one lot only: read more.
but the hill-country shall be thine; for though it is a forest, thou shalt cut it down, and the goings out thereof shall be thine; for thou shalt drive out the Canaanites, though they have chariots of iron, and though they are strong.
