'Mouth of the Cave' in the Bible

Joshua said, “Roll large stones against the mouth of the cave, and station men by it to guard the kings.

Then Joshua said, “Open the mouth of the cave, and bring those five kings to me out of there.”

At sunset Joshua commanded that they be taken down from the trees and thrown into the cave where they had hidden. Then large stones were placed against the mouth of the cave, and the stones are there to this day.
