'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, Thou shalt not smite them: wouldst 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.

That they may want bread and water, and be astonished one with another, and consume away for their iniquity.
