'Mouth of the Cave' in the Bible

Joshua said, “Roll large stones against the mouth of the cave, and assign men by it to guard them,

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

It came about at sunset that Joshua gave a command, and they took them down from the trees and threw them into the cave where they had hidden themselves, and put large stones over the mouth of the cave, to this very day.
