Joshua 17:15-16

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."

16The people of Joseph said, "The hill country is not enough for us. Yet all the Canaanites who dwell in the plain have chariots of iron, both those in Beth-shean and its villages and those in the Valley of Jezreel."
