Joshua 17:14-16

And the children of Joseph spake unto Joshua, saying, Why hast thou given me but one lot and one part for an inheritance, seeing I am a great people, forasmuch as hitherto Jehovah hath blessed me? And Joshua said unto them, If thou be a great people, get thee up to the forest, and cut down for thyself there in the land of the Perizzites and of the Rephaim; since the hill-country of Ephraim is too narrow for thee. And the children of Joseph said, The hill-country is not enough for us: and all the Canaanites that dwell in the land of the valley have chariots of iron, both they who are in Beth-shean and its towns, and they who are in the valley of Jezreel.
