Eruvin 74 The new Rav in town

One of the biggest causes of tension between a new Rav and his community almost invariably involves differences between his minhagim(customs) and the existing practise of the community.

Even the smallest of minhagim such as whether to say “shir shel yom” before or after the leining on shabbos can become a source of major friction and it takes a very mature Rav and community to learn how to fit in with one another for the sake of the new relationship.

However toxic such arguments can become, they pale in relation to conflicts regarding matters of actual halacha, where the previous Rav permitted something and the new Rav decides to forbid it, or (though less common perhaps) vice versa.

The role of מנהג המקום  (the established custom of the place) is very prevalent in halacha (see Mishna Pesachim 4/1 and the related Gemara for perhaps the most important primary source on the subject,) yet so is the authority of the מרה דאתרה (the Rav of the place), and the requirement to listen to the שופטים אשר יהיו בימים ההם (the judge at the current time [Devarim 19/17  ])

As usual, a comprehensive study of all related primary sources is necessary to reach any conclusions on the subject, something which is beyond both the scope of a daf post and my own personal scope.

However, in keeping with our model of “book-marking” relevant sources as we move through the daf cycle, I believe it is worth noting that there seems to be a very strong ראיה (proof) from the current daf regarding the authority of a new Rabbi, at least when it comes to imposing his stringent views on the community.

At the bottom of Eruvin 74b, the opinion of Rav is noted that in order for a מבוי to be treated with the leniencies of a מבוי (as opposed to a חצר,) there need to be courtyards and houses that open to it, understood to mean at least 2 courtyards with 2 houses each.

If it meets that rule, does not exceed the maximum width of 10 amos allowed for a מבוי, and has a width that is less than its length, the fourth open side along the width may be closed with a pole or beam, as discussed at the beginning of the chapter.

Otherwise, the fourth side needs to more substantially closed, as we have also seen earlier.

This rule of Rav is not universally accepted by any means, and various top Amoraim, including Shmuel and even Rabbi Yochanan, are more lenient.

For our purposes, we shall focus on Shmuel’s view, which holds that even one courtyard and one house is sufficient.

The Gemara relates that רב ברונא  was saying over Shmuel’s lenient view  and Rabbi Elazar of Rav’s school of learning queried whether Shmuel could really have held that way.

When רב ברונא  replied in the affirmative, Rabbi Elazar asked him to show him where Shmuel was staying, so that he could confront him over this.

When he met him, and Shmuel confirmed that he had indeed ruled this way, he asked Shmuel how he could possibly hold this way, seeing as he  had also said that regarding Eruvin, we only follow the principle    that a מבוי לחצרות כחחצר לבתים (An alley is to courtyards what a courtyard is to houses,) in other words, just like a courtyard opens to more than one house, so also מבוי must open to more than one courtyard.

Shmuel was silent at this point, and the story ends.

The Gemara wishes to know whether Shmuel retracted his lenient ruling based on the above argument or not- (silence is sometimes take as admission, but also sometimes taken as simply ignoring the argument due to its lack of weight)

In order to answer this question, the Gemara brings another story:

There was a certain מבוי in which a single person(or family)  איבות בר איהי lived- in other words, aמבוי  which serves just his courtyard.

He marked the open side with one post, as per the laws of a מבוי, and Shmuel consented to what he had done, in keeping with his view that one courtyard is sufficient.

Rav Anan then came and took the pole down, demonstratively forbidding what had been done.

The owner expressed his surprise as to how Rav Anan could simply come and invalidate the מבוי  which he had been relying on all this time with the support of Mar Shmuel himself (note the stress of the title “Mar”- a title denoting seniority.)

The story ends there and although Rav Anan does not seem to have answered the owner, it appears that his pleas were in vain and that Rav Anan’s stringent ruling was now accepted.

Yet the Gemara deduces from this that Shmuel never retracted his leniency and stuck to his leniency till the end.

The later deduction is not accepted for another reason we shall explore later, but we shall focus  first on the story as stated and its relevance to our discussion.

Firstly, let us attempt to clarify the facts.

Whereas we know that Shmuel had given permission to איבות בר איהי to mark his “private” מבוי  and Rav Anan later came and removed it, it is not clear from the Gemara

  1. Whether Shmuel was the Rav of that particular town initially and later replaced by Rav Anan, or simply a visitor whose ruling was accepted due to his great stature and later rejected due to another great visitor’s counter-ruling.
  2. Whether Shmuel had died when Rav Anan gave his new ruling, or whether he had simply left his position in the town or had gone back home.

At least from Rashi, it is evident that Shmuel had died before Rav Anan “overruled” him.

Why Rashi makes this “assumption” does not seem clear from the actual narrative, but could be based on סברא (logic) ,normative halacha, or simple historical fact

Given that Shmuel was the leading Amora of his time, together with Rav, it does not seem likely that Rav Anan would be able to rescind his ruling as long as he was still alive, and he might not even have been halachically permitted to do so.

This would be even less likely if this מבוי was in Shmuel’s territory of נהרדעא, where he was in charge until he died, and even less so given that Rav Anan appears to have been a student of Shmuel (see for example Eruvin 95a where he quotes things that he learnt from him.)

Although we have not eliminated the possibility that Shmuel could have been a “visiting Gadol,” it seems more probably that his view was accepted against Rav’s stringent view primarily because it was on his turf.

If we accept this as a given, then the case is now clearer:

The story took place in Shmuel’s area of authority , he permitted the מבוי, and his ruling was accepted.

After he died, Rav Anan become the new accepted authority there, and ruled stringently like Rav.

Despite the owner’s protests, it seems that Rav Anan’s stringent ruling was now accepted as binding.

If this conclusion is correct, it would follow that a new Rabbi may indeed rule stringently against the previous Rabbi under at least certain circumstances, namely if there is already precedent from an equal or greater authority (such as Rav) for the stringency, and if the previous Rabbi is no longer alive.

In the absence of the above 2 conditions, it would be hard to use this case as any form of precedent.

We should also note that the Gemara continues to refute the proof from this that Shmuel never retracted his lenient view, and answers that it is possible that he had retracted, but permitted the מבוי  for other reasons which no longer applied in Rav Anan’s time, something the owner never understood.

This reasoning was the fact that there was also a shul open to the מבוי  which counted as a second חצר, due to it being used for sleeping quarters for the shul supervisor (I have followed what seems to be the simple flow of the sugya acc Rashi, but see also Tosfos Rid. )

Shmuel simply followed his view that the main factor regarding what defines one’s home in terms of the laws of Eruvin is the place where one sleeps, and not the place where one eats.

The owner did not understand that and held that the place where one eats is what counts.

As a result, he held that Seeing as the caretaker ate somewhere else, the shul was not considered his home as far as the eruv is concerned, and the shul thus did not count as an inhabited courtyard- he thus (incorrectly) assumed that Shmuel’s permission was based on his original leniency permitting one courtyard.

According to this, Rav Anan did not necessarily repeal Shmuel’s permission because he disagreed with him on the halacha- the facts might simply have changed and the shul might no longer have been used for the caretaker’s sleeping quarters, leaving the מבוי  with only one valid courtyard.

For our purposes, seeing that the Gemara accepts this as an alternative view of what happens, there is no longer any definite proof that Rav Anan had repealed Shmuel’s lenient view- Shmuel himself might have retracted it long ago and Rav Anan was, unknown to the owner, simply adapting the same law to the new circumstances!

Despite the above “curve-ball,” the Gemara only brought this alternative in order to show that it is possible the Shmuel retracted- it does not conclude that he did retract and this was the correct version of events, and does not seem bothered at all by the clear implication of the first explanation that Rav Anan did indeed repeal Shmuel’s leniency.

This explanation also seems more likely as if it was simply a question of misunderstanding Shmuel’s reasoning, it stand to reason that some effort would to simply explain to the owner what Shmuel’s real reasoning was  (though it could be that given his entrenched view that the place of eating is “ikar”, the owner would never have accepted that Shmuel possibly held differently.)

As such, this Gemara certainly seems to offer some evidence, if not total proof, that a new Rabbi of a town may repeal leniencies of the previous Rabbi, at least subject to the 2 conditions mentioned above, namely that the previous Rabbi has died and that the stringency already has precedent from an equally rate or authority.

Though the Gra admittedly brings a different source for this, it is interesting that this indeed appears to be  the conclusion of the Rema (C.M 25/2,) though no mention of these two conditions seem to be made there, nor even of the need for him to be the official Rabbi of the city, and many poskim extend this rule to when the new Rabbi is more lenient than the previous one as well- hopefully we shall get a chance to follow up on this when we get to the next relevant sugya.
