2 Kings 1:8 (KJV)

And they said unto him, There came a man up to meet us, and said unto us, Go, turn again unto the king that sent you, and say unto him, Thus saith the Lord, Is it not because there is not a God in Israel, that thou sendest to enquire of Baal–zebub the god of Ekron? therefore thou shalt not come down from that bed on which thou art gone up, but shalt surely die.

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.
