Joshua 17:15-16

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.”

16The sons of Joseph said, “The hill country is not enough for us, and all the Canaanites who live in the valley have iron chariots, both those who are in Beth-shean and its towns and those in the Valley of Jezreel.”
