'Bread and Water' in the Bible

For it was so, when Jezebel cut off the prophets of the LORD, that Obadiah took a hundred prophets, and hid them by fifty in a cave, and fed them with bread and water.)

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

And he answered, You shall not slay them: would you slay those whom you have taken captive with your sword and with your bow? set bread and water before them, that they may eat and drink, and go to their master.

That they may lack bread and water, and be dismayed one with another, and waste away for their iniquity.
