Joshua 17:15-16

15And Joshua answered them, If thou art a great people, then go up to the forest, and cut down for thyself there in the land of the Perizzites and of the giants, if mount Ephraim is too small for thee.1 16And the children of Joseph said, The hill 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 of Bethshean and its towns, and they who are of the valley of Jezreel.
