Supernatural Fire

QUESTION: In Lev. 10:2 we read, "and a fire went out from the Lord and devoured them, and they died before the Lord." What authority is there for stating that they were killed by lightning?

ANSWER: Only a few minutes before this (9:24) "fire from before the Lord had consumed the sacrifice." It is quite certain that both fires were supernatural, for they are both spoken of in the same terms. The one consumed the burnt offering in token of the sacred nearness, and the other devoured the blasphemers as if they had been carrion.
