1 Kings 18:44-45

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.

45And it came to pass in the mean while, that the heavens became black [with] clouds and wind, and there was a great pour of rain. And Ahab got on the chariot, and went to Jizreel.
