1 Kings 18:3-5

So Ahab summoned Obadiah, who was in charge of the palace. (Obadiah was a devoted follower of the LORD. Once when Jezebel had tried to kill all the LORD’s prophets, Obadiah had hidden 100 of them in two caves. He put fifty prophets in each cave and supplied them with food and water.) Ahab said to Obadiah, “We must check every spring and valley in the land to see if we can find enough grass to save at least some of my horses and mules.”
