Joshua 17:13-15
English Standard Version
14Then the people of Joseph spoke to Joshua, saying, "Why have you given me but one lot and one portion as an inheritance, although I am a numerous people, since all along the Lord has blessed me?"
15And Joshua said to them, "If you are a numerous people, go up by yourselves to the forest, and there clear ground for yourselves in the land of the Perizzites and the Rephaim, since the hill country of Ephraim is too narrow for you."
