1 Kings 18:41-44 (KJV)

41 And Elijah said unto Ahab, Get thee up, eat and drink; for there is a sound of abundance of rain. 42 So Ahab went up to eat and to drink. And Elijah went up to the top of Carmel; and he cast himself down upon the earth, and put his face between his knees, 43 And said to his servant, Go up now, look toward the sea. And he went up, and looked, and said, There is nothing. And he said, Go again seven times. 44 And it came to pass at the seventh time, that he said, Behold, there ariseth a little cloud out of the sea, like a man’s hand. And he said, Go up, say unto Ahab, Prepare thy chariot, and get thee down, that the rain stop thee not.
