Joshua 17:14-18

Then the sons of Joseph spoke to Joshua, saying, “Why have you given me only one lot and one portion as an inheritance, though I am a numerous people whom the Lord has blessed up to this point?”

And Joshua said to them, “If you are a numerous people, go up to the forest and clear a place for yourself there in the land of the Perizzites and of the Rephaim, since the hill country of Ephraim is too narrow for you.”

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

But Joshua spoke to the house of Joseph, to Ephraim and Manasseh, saying, “You are a numerous people and have great power; you shall not have one lot only,

but the hill country shall be yours. For though it is a forest, you shall clear it, and to its farthest borders it shall be yours; for you shall drive out the Canaanites, even though they have iron chariots and though they are strong.”
