Joshua 17:17-18

17Then Joshua said to the tribes of Ephraim and Manasseh, the descendants of Joseph, “Since you are so large and strong, you will be given more than one portion.

18The forests of the hill country will be yours as well. Clear as much of the land as you wish, and take possession of its farthest corners. And you will drive out the Canaanites from the valleys, too, even though they are strong and have iron chariots.”
