Joshua 17:14-15

14Then the children of Joseph spoke to Joshua, saying, “Why have you given us only one lot and one share to inherit, since we are a great people, inasmuch as the Lord has blessed us until now?”

15So Joshua answered them, “If you are a great people, then go up to the forest country and clear a place for yourself there in the land of the Perizzites and the giants, since the mountains of Ephraim are too confined for you.”
