2 Kings 1:9-10

9The king sent an army officer with 50 men to Elijah. When the officer found Elijah sitting on top of a hill, he told Elijah, “Man of God, the king says, ‘Come down.’ ”

10Elijah answered the officer, “If I’m a man of God, fire will come from heaven and burn up you and your 50 men.” Then fire came from heaven and burned up the officer and his 50 men.
