Joshua 17:15; Joshua 17:18

15 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."

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