'Forest' in the Bible

“If you have so many people,” Joshua replied to them, “go to the forest and clear an area for yourselves there in the land of the Perizzites and the Rephaim, because Ephraim’s hill country is too small for you.”

because the hill country will be yours also. It is a forest; clear it and its outlying areas will be yours. You can also drive out the Canaanites, even though they have iron chariots and are strong.”
