1 Kings 18:2-8

So Elijah went to appear before Ahab. Meanwhile, the famine had become very severe in Samaria. 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.” So they divided the land between them. Ahab went one way by himself, and Obadiah went another way by himself. As Obadiah was walking along, he suddenly saw Elijah coming toward him. Obadiah recognized him at once and bowed low to the ground before him. “Is it really you, my lord Elijah?” he asked. “Yes, it is,” Elijah replied. “Now go and tell your master, ‘Elijah is here.’”
