'Bread and Water' 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);

Was it not told my lord what I did when Jezebel slew the prophets of Jehovah, how I hid a hundred men of Jehovah's prophets by fifty in a cave, and maintained them with bread and water?

And he said, Thou shalt not smite them: wouldest thou smite those whom thou hast taken captive with thy sword and with thy bow? Set bread and water before them, that they may eat and drink, and go to their master.

because bread and water shall fail them, and they shall be astonied one with another, and waste away in their iniquity.
