A friend who sits a few rows behind me in synagogue and is a regular reader of the Daily Dose asked me recently: Is all this really necessary? It’s a reasonable question. The conversation in Tractate Zevachim is laser focused on the minutia of the sacrificial system, and the potential ways it can go wrong, at a level of detail that can feel a bit over the top. My friend’s question is one that many of us have been asking of late. You might be surprised to discover that, on today’s daf, the Talmud itself asks the same question, although in a more focused way.
As part of the sacrificial process for a burnt offering, the carcass of the animal is taken apart before it is burnt on the altar. In a mishnah on page 77b, we encountered a dispute between Rabbi Eliezer and the rabbis about what to do if the limbs of a burnt offering become intermingled with those of an animal that was discovered to be blemished as it was slaughtered and is no longer fit to be offered.
Rabbi Eliezer argues that if one of the limbs from the mix has already been offered, we can assume it was a blemished one and we can treat those that remain as fit to be sacrificed. The rabbis, on the other hand, say that even if all of the limbs save one have already been offered at the time of our discovery, the one that remains is considered suspect of being unfit and cannot be sacrificed.
A similar dispute appeared toward the end of yesterday’s daf, this time about what to do when a cup of the blood of a blemished offering becomes intermingled with cups of blood fit for offering. Here again, Rabbi Eliezer says that if a cup of blood has already been presented, we can assume it was the unfit one and the rest can be offered without concern. The rabbis, as they did before, disagree, ruling that even if the blood in all the cups was sacrificed except for one, the remaining cup is unfit and must be poured down the drain.
The Gemara is curious: Do we really need both of these cases? Given that Rabbi Eliezer and the rabbis are consistent in their views, couldn’t we just infer the details of one disagreement from the other? Do we really need a mishnah about mixed up limbs and one about mixed up cups?
The reply:
It is necessary, as if it were stated only with regard to that case (of the limbs), one would have said that it is in that case alone that Rabbi Eliezer says (that the rest of the limbs are sacrificed) because the offering’s atonement has already been performed. But in this case (of the blood in the cups), say that Rabbi Eliezer concedes to the rabbis.
The limbs of a burnt offering are burnt on the altar after the blood of the sacrifice has been offered and atonement has been granted. Rabbi Eliezer’s leniency about offering them may be rooted in this fact. Since atonement is already granted, we can apply a more lenient standard to a mixed group of limbs. After all, they are burned only after the sacrifice has accomplished its purpose. Without the second mishnah to teach us otherwise, this line of thinking may have led us to conclude that when it comes to mixed up cups of blood, Rabbi Eliezer agrees with the rabbis.
The Gemara continues:
And if it were stated only with regard to this case (of the cups), one would have said that it is in this case alone that the rabbis say (that the blood in the rest of the cups is unfit), but in that case (of the limbs), say the rabbis concede to Rabbi Eliezer.
Using similar logic, the Gemara states that if we only had been taught the mishnah about the cups, we might conclude that the rabbis agree with Rabbi Eliezer about the limbs, as there is no reason for them to be as strict about items that are burned after atonement is complete.
So yes, both of these teachings are necessary. Had either of the two disagreements been left out, it is more than possible that the analysis of the remaining passage would have distorted the view of one of the parties to the dispute.
This answer is an important reminder to those of us who may be asking about how this tractate is relevant to us today. While the Talmud can and does teach us relevant laws and lessons for our lives today, relevance is not its goal. Its concerns lie elsewhere — maintaining the link between the rabbinic tradition in the biblical text, understanding the plurality of rabbinic opinions that are part of the canon, and providing for those who would serve as interpreters of the tradition the tools they needed to make decisions about new situations. The Talmud was preserved mainly for those in the academy — not those in the village.
It’s worth noting that the style and nature of the conversations here are not so different from the ones found in other sections of the Talmud that concern Temple rituals. Nor are they so different in tone and texture from those concerning more obviously “relevant” subject matter, like Shabbat and marriage. While Tractate Zevachim can feel distant, unfamiliar, irrelevant, gory and devoid of the storytelling and other aggadic passages many enjoy, it’s really not all that different from the rest of the Talmud. Perhaps the question is not is this really necessary, but what does this add to my understanding of the Talmud.
