'Forest' in the Bible

Joshua replied to them, "Since you have so many people, go up into the forest and clear out a place to live in the land of the Perizzites and Rephaites, for the hill country of Ephraim is too small for you."

The whole hill country will be yours; though it is a forest, you can clear it and it will be entirely yours. You can conquer the Canaanites, though they have chariots with iron-rimmed wheels and are strong."
