'Mouth of the Cave' in the Bible

And Joshua said, "Roll large stones against the mouth of the cave, and set men in front of it to guard them.

And Joshua said, "Open the mouth of the cave, and bring to me those five kings from the cave."

And it happened {at the time of sunset}, Joshua commanded, and they took them down from the trees and threw them into the cave where they had hidden themselves, and they put large stones against the mouth of the cave, [which are there] to this very day.
