Joshua 17:16-18

16And 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 her towns, and they who are in the valley of Jezreel. 17And 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: 18but 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 be strong.
