whatever was eligible for the altar fire did not descend once it had ascended. Thus, just as the burnt-offering, which was eligible for the altar fire, did not descend once it had ascended, so whatever was eligible for the altar fire did not descend once it ascended. The Gemara interpreted the words in "This is the law of the burnt-offering: It is that which goes up on its firewood upon the altar all night into the morning." From the passage, "which goes up on its firewood upon the altar all night," the Rabbis deduced that once a thing had been placed upon the altar, it could not be taken down all night.

Rabbi Simeon suggested that one might think that law would also include an animal used for bestiality, set aside for an
