1 Kings 18:44-45

The seventh time, the servant said, “I see a small cloud, the size of a human fist, coming from the sea.” Elijah told the servant, “Go to Ahab and tell him to get his chariot ready and go home now. Otherwise, the rain will stop him.” After a short time the sky was covered with dark clouds. The wind began to blow, and soon a heavy rain began to fall. Ahab got in his chariot and started back to Jezreel.
