2 Kings 1:10-12

10Elijah replied to the captain, ‘If I am really a man of God, fire will come down from the sky. It will destroy you and your 50 soldiers.’ Then fire did come down from the sky. It destroyed the captain and his 50 soldiers.

11Then the king sent another captain with 50 more soldiers to fetch Elijah. The captain went up and he said to Elijah, ‘Man of God, the king says, “Come down immediately!” ’

12Elijah answered, ‘If I am really a man of God, fire will come down from the sky. It will destroy you and your 50 soldiers.’ Then fire from God did come down from the sky. It destroyed the captain and his 50 soldiers.
