1 Kings 18:44-45

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.’ ”

45Now it happened in the meantime that the sky became black with clouds and wind, and there was a heavy rain. So Ahab rode away and went to Jezreel.
