'Mouth of the Cave' in the Bible

And Joshua will say, Roll great stones to the mouth of the cave, and set men over it to watch them.

And Joshua will say, Open the mouth of the cave and bring forth to me these five kings out of the cave.

And it will be at the time of the going down of the sun Joshua commanded, and they will take them down from the trees and cast them into the cave where they were hid there; and they will put great stones upon the mouth of the cave till this self-same day.
