1 Kings 18:5-8

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.’”
