1 Kings 18:43-44

And he said to his servant, Go up now, look toward the sea. And he went up, and looked, and said, There is nothing. And he said, Go again seven times. And it came to pass at the seventh time, that he said, Behold, there ariseth a cloud out of the sea, as small as a man’s hand. And he said, Go up, say unto Ahab, Make ready thy chariot, and get thee down, that the rain stop thee not.
