Joshua 17:14-16
17:14 The descendants of Joseph said to Joshua, “Why have you assigned us only one tribal allotment? After all, we have many people, for until now the Lord has enabled us to increase in number.”
17:15 Joshua replied to them, “Since you have so many people, go up into the forest and clear out a place to live in the land of the Perizzites and Rephaites, for the hill country of Ephraim is too small for you.”
17:16 The descendants of Joseph said, “The whole hill country is inadequate for us, and the Canaanites living down in the valley in Beth Shean and its surrounding towns and in the Valley of Jezreel have chariots with iron-rimmed wheels.”
