1 Kings 18:44-45

44And at the seventh time he said, "Behold, a little cloud like a man's hand is rising from the sea." And he said, "Go up, say to Ahab, 'Prepare your chariot and go down, lest the rain stop you.'"

45And in a little while the heavens grew black with clouds and wind, and there was a great rain. And Ahab rode and went to Jezreel.
