Close Encounters With Talmud

Are Truffles Food?

As our Talmud column returns, debates over Oral Law range from the existential to the mundane

Can Boundaries Cause Unity?

Two exhibits ask whether eruvs speak to our essential beings or just replicate the conditions of our wanderings

But wait, the Gemara goes on. Surely Rabbi Yehudah would also have agreed with this principle: That can’t be the grounds of the disagreement. Why, then, does he still allow an eruv in a graveyard? It is because, the Gemara speculates, he has a different definition of what it means to derive a benefit: “He is of the opinion that mitzvot were not given for the purpose of our deriving benefit from them.” That is to say, an action performed as part of a mitzvah does not qualify as a personal benefit, even if it might seem to be to the advantage of the person doing it.

Here the Gemara objects once again. Wouldn’t all the rabbis agree to this principle, too? So, then where does the conflict between Yehudah and his opponents lie? It lies, the Gemara now suggests, in the purpose for which an eruv can be made. To Rabbi Yehudah, an eruv can be made only in order to facilitate the performance of a mitzvah. Say, Rashi explains, that you had a sick friend who lived 3,000 amot away from you. In order to visit him on Shabbat, you could make an eruv that would bring your friend inside your techum. But you couldn’t, as I understand it, make an eruv just because you wanted to take a walk: That would be a mere personal benefit, and you can’t make an eruv for such a purpose.

But the rabbis—and by this phrase the Talmud means the majority of rabbis, the consensus—disagree. They hold that “an eruv may be made even to facilitate the performance of a discretionary act.” You don’t need a specific mitzvah in mind to justify making an eruv; you can make one if you happen to feel like it.

Now we must trace the chain of the argument backward, in order to understand how the rabbis and Yehudah arrived at their initial disagreement. All parties agree that it is prohibited to derive personal benefit from a forbidden object, and that a grave is a forbidden object. To Yehudah, an eruv is only for performing mitzvot; mitzvot are not for personal benefit; so establishing an eruv does not confer a personal benefit; so an eruv can be made on a gravesite, since it does derive any benefit from a forbidden object: QED. The rabbis, on the other hand, hold that an eruv can be for personal benefit, and so an eruv can’t be made on a gravesite, since this would involve deriving a benefit from a forbidden object.

But we’re not done yet. Now Rav Yosef enters the debate with an entirely different explanation for the disagreement between Yehudah and the rabbis. They all agreed, Yosef believes, that an eruv is only for mitzvot, and that mitzvot are not personal benefits. Where they differed was over the status of the eruv food once Shabbat begins. Recall that it is not necessary to be able to actually eat the food used to establish a Shabbat residence. Because of this, Yehudah might have argued, the placement of food on a grave does not involve getting any benefit from the grave, since the Jew who places the food there has no intention of returning to eat it; he is “indifferent to the safeguarding of the eruv food.” This may be so, the rabbis could respond, but after all “if he needs it, he may eat it”: Thus there is a potential personal benefit from the gravesite, and this is enough to disqualify it.

And so the debate ends. What’s remarkable about it is that, pragmatically speaking, we know no more at the conclusion than we did at the beginning. If the Talmud simply wanted to tell us what to do and not to do, it could have simplified things greatly by just giving us the authoritative halachic ruling: An eruv cannot be established at a gravesite. But then we would have missed out on the distinctively Talmudic pleasure of comprehensive understanding.

Fat_Man says:

So, is it in accordance with Halachah to put a plastic bag over your head?

41953 says:

That is one taboo that should be taboo

Sam the Man says:

Silly, very very silly. I imagine most of the Talmud is though.

Thank you for the analysis. However if the point of disagreement between R Yehuda and the Rabbis about whether a Kohen can construct an eruv in a graveyard is whether an eruv can be constructed for mitzvot only or can also be used for discretionary purposes… It would seem that the Rabbis do not argue on the issue of whether a moving tent is a tent. And the fact that the halachah rules that an eruv may not be constructed in graveyard does not lead to the inference that a moving tent is not a tent. To the contrary the opposite seems true. Unless I missed something…

Regarding the kohen on the airplane: Assuming you didn’t get to it yet, but a discussion takes place in Eruvin 43 about tchum shabbat not applying over 10 tfachim – the proof: Eliyahu Ha Nava/Elija the prophet appeared in two cities on the same Shabbat – apparently not a problem, since he flew. Don’t know the laws of kohanim, but can we not extrapolate from this same principle (that you are not in fact within a certain domain if you are more than 10 tfachim above it) that this man’s concern is unfounded? Also – going out on a limb, but I think it’s slightly more reasonable to assume that this man was actually concerned about a deceased body that he may have had prior knowledge about being on the plane.

41953 says:

Elijah flew? And did Jesus walk on water too?

Grigalem says:

Relying on your imagination instead of your knowledge and research is silly … and foolish.

Grigalem says:

In your case, yes.

Fat_Man says:

Nice. Yet another reason not to be orthodox

Grigalem says:


What is?

elixelx says:

In the Talmud, you dolts, the destination is NOT the point! It is NEVER the point! The JOURNEY is, because that is what life is!
Saying you find argument for the sake of argument silly is saying you prefer to remain ignorant, a slave, ready to do what massa tells you to do! but free men argue, free men have points of view, different points of view, changing points of view, points of view that one can adopt or discard as your brain sees fit!
That’s why two jews can have three, or three hundred, opinions, whereas you, you eunuchs, stick with one and only one!

elixelx says:

Why not?

elixelx says:

Then don’t read the Talmud. Do what your imagination tells you is sufficient…and die in your own ignorance!

elixelx says:

Why not?

elixelx says:

So, don’t be orthodox! I’m sure you have plenty of other reasons…!
But that’s the point of this debate! If you scoff when you hear it and come to the POV that it so disgusts you that you don’t want to be ‘orthodox’ good luck to you! Do what you think is right!
But note; while you abrogate to yourself the right to do as you please you laugh at a man who does as he pleases!
Now that, you see, makes you a bigot!

Fat_Man says:

I am not sniggering at the Torah. I am sniggering at people who can talk themselves into the proposition that they need to seal themselves into plastic bags while ridding in an 80 ton metal airliner because of the emanations of things at ambient temperature eight miles away.

He certainly has the right to do it, and sensible men have the right to laugh.

BTW, you misused the word “abrogate”.

Fat_Man says:

Grigalem. It is your hostility.

Grigalem says:

Yup. That’s what you get when you ask some to clarify their comments — accusations of hostility from hostile children.

Feeling abrogated, sonny?

elixelx says:

My bad on the phrasing: ‘You abrogate his right to do as he pleases while claiming a right to do as you please!”

Paula Levin says:

im loving this series! as an orthodox female, i havent had much exposure to mishnah and gemarah, so this series is a fascinating introduction, and i like the curious and respectful tone of the author
