'Mouth of the Cave' in the Bible

And Joshua said, roll great stones unto the mouth of the cave and appoint men thereto, for to keep them.

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

And when Elijah heard it, he covered his face with his mantle, and went out and stood in the mouth of the cave. And see, there came a voice unto him and said, "What doest thou here Elijah?"
