1 Kings 18:43-44

43and said to his servant, “Go up now, look toward the sea.” So he went up and looked, and said, “There is nothing.” And seven times he said, “Go again.”

44Then it came to pass the seventh time, that he said, “There is a cloud, as small as a man’s hand, rising out of the sea!” So he said, “Go up, say to Ahab, ‘Prepare your chariot, and go down before the rain stops you.’ ”
