'Fire of God' in the Bible

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

While he was still speaking, there also came another and said, The fire of God has fallen from the heavens and has burned up the sheep and the servants, and destroyed them. And I only have escaped alone to tell you.
