1 Kings 18:3-5

And Ahab sent for Obadiah, the controller of the king's house. (Now Obadiah had the fear of the Lord before him greatly; For when Jezebel was cutting off the prophets of the Lord, Obadiah took a hundred of them, and kept them secretly in a hole in the rock, fifty at a time, and gave them bread and water.) And Ahab said to Obadiah, Come, let us go through all the country, to all the fountains of water and all the rivers, and see if there is any grass to be had for the horses and the transport beasts, so that we may be able to keep some of the beasts from destruction.
