'Fire of God' in the Bible

And Elijah answereth and speaketh unto them, 'If I am a man of God, fire doth come down from the heavens, and consume thee and thy fifty;' and fire of God cometh down from the heavens, and consumeth him and his fifty.

While this one is speaking another also hath come and saith, 'Fire of God hath fallen from the heavens, and burneth among the flock, and among the young men, and consumeth them, and I am escaped -- only I alone -- to declare it to thee.'
