'Cave' in the Bible

and it cometh to pass, in Jezebel's cutting off the prophets of Jehovah, that Obadiah taketh a hundred prophets, and hideth them, fifty men in a cave, and hath sustained them with bread and water --

'Hath it not been declared to my lord that which I have done in Jezebel's slaying the prophets of Jehovah, that I hide of the prophets of Jehovah a hundred men, fifty by fifty in a cave, and sustained them with bread and water?

And he cometh in there, unto the cave, and lodgeth there, and lo, the word of Jehovah is unto him, and saith to him, 'What -- to thee, here, Elijah?'

and it cometh to pass, at Elijah's hearing it, that he wrappeth his face in his robe, and goeth out, and standeth at the opening of the cave, and lo, unto him is a voice, and it saith, 'What -- to thee, here, Elijah?'
