1 Kings 18:42-44

So Ahab went off to eat and drink, but Elijah climbed to the top of Carmel, bent down to the ground and put his face between his knees. “Go and look toward the sea,” he told his servant. And he went up and looked. “There is nothing there,” he said. Seven times Elijah said, “Go back.” The seventh time the servant reported, “A cloud as small as a man’s hand is rising from the sea.” So Elijah said, “Go and tell Ahab, ‘Hitch up your chariot and go down before the rain stops you.’ ”
