1 Kings 18:44-45

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!’”

45And soon the sky was black with clouds. A heavy wind brought a terrific rainstorm, and Ahab left quickly for Jezreel.
