1 Kings 18:43-44

43Then he said to his servant, “Go and look out toward the sea.” The servant went and looked, then returned to Elijah and said, “I didn’t see anything.” Seven times Elijah told him to go and look.

44Finally the seventh time, his servant told him, “I saw a little cloud about the size of a man’s hand rising from the sea.” Then Elijah shouted, “Hurry to Ahab and tell him, ‘Climb into your chariot and go back home. If you don’t hurry, the rain will stop you!’”
