2 Kings 1:9-10

Then he sent a captain with his fifty men to Elijah. The captain went to Elijah, who was sitting on top of the hill, and said to him, “Man of God, the king says, ‘Come down!’ ” Elijah answered the captain, “If I am a man of God, let fire come down from heaven and burn up you and your fifty men.” Then fire came down from heaven and burned up the captain and his fifty men.
