2 Kings 1:9-11

9 And he sent to him a commander of fifty with his fifty. And he went up to him. And, behold, he sat on the top of a hill. And he spoke to him, Man of God! The king has said, Come down.

10 And Elijah answered and said to the commander of fifty, If I [am] a man of God, then let fire come down from the heavens and burn up you and your fifty. And there came down fire from the heavens and burned up him and his fifty.

11 And he turned and he sent to him another commander of fifty with his fifty. And he answered and said to him, Man of God! So says the king, Come down quickly.
