2 Kings 1:9 (KJV)

And he said unto them, What manner of man was he which came up to meet you, and told you these words?

And they answered him, He was an hairy man, and girt with a girdle of leather about his loins. And he said, It is Elijah the Tishbite.

Then the king sent unto him a captain of fifty with his fifty. And he went up to him: and, behold, he sat on the top of an hill. And he spake unto him, Thou man of God, the king hath said, Come down.

And Elijah answered and said to the captain of fifty, If I be a man of God, then let fire come down from heaven, and consume thee and thy fifty. And there came down fire from heaven, and consumed him and his fifty.

Again also he sent unto him another captain of fifty with his fifty. And he answered and said unto him, O man of God, thus hath the king said, Come down quickly.
