1 Kings 18:2-8

And Elijah went to show himself unto Ahab. And the famine was sore in Samaria. And Ahab called Obadiah, who was over the household. (Now Obadiah feared Jehovah greatly: for it was so, when Jezebel cut off the prophets of Jehovah, that Obadiah took a hundred prophets, and hid them by fifty in a cave, and fed them with bread and water.) And Ahab said unto Obadiah, Go through the land, unto all the fountains of water, and unto all the brooks: peradventure we may find grass and save the horses and mules alive, that we lose not all the beasts. So they divided the land between them to pass throughout it: Ahab went one way by himself, and Obadiah went another way by himself. And as Obadiah was in the way, behold, Elijah met him: and he knew him, and fell on his face, and said, Is it thou, my lord Elijah? And he answered him, It is I: go, tell thy lord, Behold, Elijah is here.
