Joshua 17:16-18

16And the children of Joseph said, The hill-country will not be enough for us; and all the Canaanites that dwell in the land of the valley have chariots of iron, those that are of Beth-shean and its dependent villages, and those that are in the valley of Jizreel. 17And Joshua spoke to the house of Joseph, 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, as it is a wood, thou shalt cut it down, and its outgoings shall be thine; for thou shalt dispossess the Canaanites, though they have iron chariots; for they are powerful.
