Joshua 17:15-16

15Joshua answered them, “If you have so many people that the hill country of Ephraim is too small for you, go to the forest and clear for yourself an area in the land of the Perizzites and the Rephaim.”

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