'Fire of God' in the Bible

Elijah answered them, “If I am a man of God, let fire come down from heaven and consume you and your fifty [fighting men].” And the fire of God came down from heaven and consumed him and his fifty.

While he was still speaking, another [messenger] also came and said, “The fire of God (lightning) has fallen from the heavens and has burned up the sheep and the servants and consumed them, and I alone have escaped to tell you.”
