Joshua 17:15-16

15“If you have so many people,” Joshua replied to them, “go to the forest and clear an area for yourselves there in the land of the Perizzites and the Rephaim, because Ephraim’s hill country is too small for you.”

16But the descendants of Joseph said, “The hill country is not enough for us, and all the Canaanites who inhabit the valley area have iron chariots, both at Beth-shean with its surrounding villages and in the Jezreel Valley.”
