Joshua 17:14-15

14The sons of Joseph spoke to Joshua, saying, “Why have you given us only one lot and one portion as an inheritance, when we are a numerous people whom the Lord has so far blessed?”

15Then Joshua replied, “If you are a numerous people, go up to the forest and clear ground for yourselves there in the land of the Perizzites and the Rephaim, since the hill country of Ephraim is too narrow for you.”
