1 Kings 18:43-44

43And 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.

44And it came to pass at the seventh time that he said, Behold there is a cloud, small as a man's hand, arising out of the sea. And he said, Go up, say to Ahab, Harness and go down, that the pour of rain stop thee not.
