Joshua 17:15-16

15“If you are so numerous,” Joshua answered, “and if the hill country of Ephraim is too small for you, go up into the forest and clear land for yourselves there in the land of the Perizzites and Rephaites.”

16The people of Joseph replied, “The hill country is not enough for us, and all the Canaanites who live in the plain have chariots fitted with iron, both those in Beth Shan and its settlements and those in the Valley of Jezreel.”
