Joshua 17:15-16

15And Joshua said unto them, If thou art a great people, then get thee up to the wood, and cut down for thyself there in the land of the Perizzites and of the giants, if the hill-country of Ephraim is too narrow for thee.

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.
