Without regard to these followers of Korah, who were swallowed up by the earth, the two hundred and fifty men who had offered incense with Aaron found their death in the heavenly fire that came down upon their offering and consumed them. But he who met with the most terrible form of death was Korah. Consumed at the incense offering, he then rolled in the shape of a ball of fire to the opening in the earth, and vanished.
There was a reason for this double punishment of Korah. Had he received punishment by burning alone, then those who had been swallowed by the earth, and who had failed to see Korah smitten by the same punishment, would have complained about God's injustice, saying: "It was Korah who plunged us into destruction, yet he himself escaped it." Had he, on the other hand, been swallowed by the earth without meeting death by fire, then those whom the fire had consumed would have complained about God injustice that permitted the author of their destruction to go unpunished.
Now, however, both those who perished by fire and those who were swallowed up by the earth witnessed their leader share their punishment.
