'Mouth of the Cave' in the Bible

And Joshua said, Roll ye great stones against the mouth of the cave, - and set over it men, to watch them;

Then said Joshua, Open ye the mouth of the cave, - and bring out unto me, these five kings, out of the cave.

And it came to pass, at the time of the going in of the sun, that Joshua gave command, and they took them down off the trees, and cast them into the cave, where they had hid themselves, - and put great stones upon the mouth of the cave, which remain , until this very day.
