'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 sky, and consume you and your fifty." The fire of God came down from the sky, and consumed him and his fifty.

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