English: It was taught: “And the sons of Aharon the kohen shall put fire on the altar” — even though fire descends from heaven, there is a mitzvah to bring [fire] from the ordinary [human source].
In the sugya: Heavenly fire is a gift; human kindling is still commanded. The verse’s “they shall put fire” is not cancelled by the miracle of fire from above. Both operate together.
Type of Learning
Force of “they shall put fire” — human kindling remains a mitzvah even when fire descends from heaven.
What Is Learned
Heavenly fire does not exempt the kohanim from kindling fire of human origin on the altar. The command to put fire is independent of the miracle of descending fire.
