1 Kings 18:3-6

Ahab called for Obadiah, who was in charge of the palace. Obadiah feared GOD—he was very devout. Earlier, when Jezebel had tried to kill off all the prophets of GOD, Obadiah had hidden away a hundred of them in two caves, fifty in a cave, and then supplied them with food and water. Ahab ordered Obadiah, “Go through the country; locate every spring and every stream. Let’s see if we can find enough grass to keep our horses and mules from dying.” So they divided the country between them for the search—Ahab went one way, Obadiah the other.
