Joshua 17
16 Ref 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.
17 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:
18 Ref 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.
