And Joshua answered them, If thou be a great people, then get thee up to the wood country, and cut down for thyself there in the land of the Perizzites and of the giants, if mount Ephraim be too narrow for thee.
And Joshua said to them, "If you are a numerous people, go up by yourselves to the forest, and there clear ground for yourselves in the land of the Perizzites and the Rephaim, since the hill country of Ephraim is too narrow for you."
Joshua replied, “If there are so many of you, and if the hill country of Ephraim is not large enough for you, clear out land for yourselves in the forest where the Perizzites and Rephaites live.”
