2 Kings 1:9-11

9 Then the king sent to Elijah a captain of fifty men with his fifty [to seize him]. He found Elijah sitting on a hilltop and said, Man of God, the king says, Come down.

10 Elijah said to the captain of fifty, If I am a man of God, then let fire come down from heaven and consume you and your fifty. And fire fell from heaven and consumed him and his fifty.

11 Again King [Ahaziah] sent to him another captain of fifty with his fifty. And he said to Elijah, Man of God, the king has said, Come down quickly!
