1 Kings 18:42-44

So Ahab went up to eat and drink. But Elijah went up to the top of Carmel; and he crouched down on the earth and put his face between his knees. He said to his servant, “Go up now, look toward the sea.” So he went up and looked and said, “There is nothing.” And he said, “Go back” seven times. It came about at the seventh time, that he said, “Behold, a cloud as small as a man’s hand is coming up from the sea.” And he said, “Go up, say to Ahab, ‘Prepare your chariot and go down, so that the heavy shower does not stop you.’ ”
