'Cave' in the Bible

and it was so, when Jezebel cut off the prophets of Jehovah, that Obadiah took a hundred prophets, and hid them by fifty in a cave, and maintained them with bread and water);

And there he went into a cave, and lodged there. And behold, the word of Jehovah came to him, and he said to him, What doest thou here, Elijah?

And it came to pass, when Elijah heard it, that he wrapped his face in his mantle, and went out, and stood in the entrance of the cave. And behold, a voice came to him and said, What doest thou here, Elijah?
