I Kings 18:3-5

And Ahab had called Obadiah, who was in charge of his house. (Now Obadiah feared the LORD greatly. For so it was, while Jezebel massacred the prophets of the LORD, that Obadiah had taken one hundred prophets and hidden them, fifty to a cave, and had fed them with bread and water.) And Ahab had said to Obadiah, “Go into the land to all the springs of water and to all the brooks; perhaps we may find grass to keep the horses and mules alive, so that we will not have to kill any livestock.”
