'Fire of God' in the Bible

And Elijah answered and said unto them, If I be a man of God, let fire come down from heaven, and consume you and your fifty men. And the fire of God came down from heaven, and consumed him and his fifty.

While he was yet speaking, there came also another, and said, The fire of God has fallen from heaven, and has burned up the sheep, and the servants, and consumed them; and I alone am escaped to tell you.
