'Fire of God' in the Bible

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

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