1 Kings 18:43-44

43And he said to his servant, “Go up now, look toward the sea.” So he went up and looked, but he said, “There is nothing.” Yet Elijah said, “Go back” seven times.

44And when he returned the seventh time, he said, “Behold, 1a cloud as small as a person’s hand is coming up from the sea.” And Elijah said, “Go up, say to Ahab, ‘Harness your chariot horses and go down, so that the heavy shower does not stop you.’”
