This source sheet provides background material for the controversy over Semicha. Translations are from Sefaria.

Source 1 These sources set forth the biblical foundations requiring Semicha for personal Korbonos

(ד) וְסָמַ֣ךְ יָד֔וֹ עַ֖ל רֹ֣אשׁ הָעֹלָ֑ה וְנִרְצָ֥ה ל֖וֹ לְכַפֵּ֥ר עָלָֽיו׃

(4) He shall lay his hand upon the head of the burnt offering, that it may be acceptable in his behalf, in expiation for him.

(א) וְאִם־זֶ֥בַח שְׁלָמִ֖ים קָרְבָּנ֑וֹ אִ֤ם מִן־הַבָּקָר֙ ה֣וּא מַקְרִ֔יב אִם־זָכָר֙ אִם־נְקֵבָ֔ה תָּמִ֥ים יַקְרִיבֶ֖נּוּ לִפְנֵ֥י יְהוָֽה׃ (ב) וְסָמַ֤ךְ יָדוֹ֙ עַל־רֹ֣אשׁ קָרְבָּנ֔וֹ וּשְׁחָט֕וֹ פֶּ֖תַח אֹ֣הֶל מוֹעֵ֑ד וְזָרְק֡וּ בְּנֵי֩ אַהֲרֹ֨ן הַכֹּהֲנִ֧ים אֶת־הַדָּ֛ם עַל־הַמִּזְבֵּ֖חַ סָבִֽיב׃

(1) If his offering is a sacrifice of well-being— If he offers of the herd, whether a male or a female, he shall bring before the LORD one without blemish. (2) He shall lay his hand upon the head of his offering and slaughter it at the entrance of the Tent of Meeting; and Aaron’s sons, the priests, shall dash the blood against all sides of the altar.
Source 2These Mishnayos set forth the basic rules of Semicha. Generally limited to personal KorbonosAn agent (Shliach) does not perform SemichaIf Semicha is not done the Korban remains validSemicha is done by placing your hands on the animals' headSemicha takes place in the Beis HaMikdashSemicha should take place immediately prior to sacrificing the animal

(ז) כל קרבנות הצבור. אין בהם סמיכה. חוץ מן הפר הבא על כל המצות. ושעיר המשתלח. רבי שמעון אומר אף שעירי עבודה זרה. כל קרבנות היחיד טעונים סמיכה. חוץ מן הבכור והמעשר והפסח. והיורש סומך ומביא נסכים וממיר:

(ח) הכל סומכין. חוץ מחרש שוטה וקטן. סומא ונכרי. והעבד והשליח והאשה. וסמיכה שירי מצוה. על הראש. בשתי ידים. ובמקום שסומכין שוחטין. ותכף לסמיכה שחיטה:

(7) All of the offerings of community do not require the laying on of hands except the bull that is offered for [the transgression] of any of the commandments, and the scapegoat. Rabbi Shimon says: also the goats offered for [the transgression] of idol worship. All the offerings of an individual require the laying on of hands except the first-born, the cattle tithe, and the pesach. And an heir may lay his hands [on them], and he may bring the libations, and [if he wrongfully] substitutes [another animal for it, it is holy].

(8) All perform the laying on of hands except for a deaf-mute, a shoteh, a minor, a blind person, a non-Jew, a slave, an agent, and a woman. The laying on of hands - the last part of the commandment [of bringing the offering] - is on the head, and [is performed] with both hands, the place they would slaughter is where the hands are laid [upon the animal], and immediately after laying hands upon it they would slaughter it.

Source 3 This Mishna describes the Rabbinic prohibition on utilizing an animal (e.g., leaning on for support) on Yom tov.

(ב) כל שחייבין עליו משום שבות. משום רשות. משום מצוה. בשבת. חייבין עליו ביום טוב. ואלו הן משום שבות. לא עולין באילן. ולא רוכבין על גבי בהמה. ולא שטין על פני המים. ולא מטפחין. ולא מספקין. ולא מרקדין. ואלו הן משום רשות. לא דנין. ולא מקדשין. ולא חולצין. ולא מיבמין. ואלו הן משום מצוה. לא מקדישין. ולא מעריכין. ולא מחרימין. ולא מגביהין תרומה ומעשר. כל אלו ביום טוב אמרו. קל וחומר בשבת. אין בין יום טוב לשבת. אלא אוכל נפש בלבד:

(2) Any [act] for which one is liable on Shabbat as a matter of shevut [restrictions established by the Sages regarding Shabbat to prevent violation of Torah-level Shabbat prohibitions, and to increase its sanctity], or as an optional matter [i.e. something not fully a mitzvah], or as a mitzvah, one is also liable [for such an act] on a holiday. And these are [the acts for which one is liable] as a matter of shevut: one may not climb a tree, and one may not ride atop an animal, and one may not swim in water, and one may not clap, nor slap [thighs], nor dance. And these are [the acts for which one is liable] as an optional matter: one may not judge [a court case], and one may not betroth, nor perform chalitzah [the ceremony performed to release a widow of a childless man from the obligation of levirite marriage], nor perform yibum [the enactment of a levirite marriage of the widow of a childless man]. And these are [the acts for which one is liable] as a mitzvah: one may not consecrate [anything to the Temple], nor vow a personal valuation, nor make something cherem [proscribed from personal use, possibly due to being dedicated to the Temple], nor raise terumah or tithes out [from one's produce]. All of these were said [to be forbidden] regarding holidays so, a fortiori, [they must also be forbidden] on Shabbat. There is no difference between [the laws of] holidays and Shabbat except only for okhel nefesh [certain types of food preparation which, though forbidden on Shabbat, are permitted on festivals].

Source 4 These Mishnayos describe the generational dispute surrounding Semicha. The juxtaposition of these two Mishnayos provides strong support for interpreting the first Mishna as also describing Semicha on Yom Tov.

(ב) יוסי בן יועזר אומר שלא לסמוך. יוסי בן יוחנן אומר לסמוך. יהושע בן פרחיה אומר שלא לסמוך. ניתאי הארבלי אומר לסמוך. יהודה בן טבאי אומר שלא לסמוך. שמעון בן שטח אומר לסמוך. שמעיה אומר לסמוך. אבטליון אומר שלא לסמוך. הלל ומנחם לא נחלקו. יצא מנחם. נכנס שמאי. שמאי אומר שלא לסמוך. הלל אומר לסמוך. הראשונים היו נשיאים. ושניים להם אב בית דין:

(ג) בית שמאי אומרים מביאין שלמים ואין סומכין עליהם. אבל לא עולות. ובית הלל אומרים מביאין שלמים ועולות וסומכין עליהם:

(2) Yose ben Yoezer says not to lean hands [on the Chagigah sacrifice]; Yose ben Yohanan says to lean hands. Yehoshua ben Perahia says not to lean hands; Nitai the Arbelite says to lean hands. Yehuda ben Tavai says not to lean hands; Shimon ben Shetach says to lean hands. Shemaya says to lean hands; Avtaliyon says not to lean hands. Hillel and Menahem did not disagree. Menahem left and Shammai entered. Shammai says not to lean hands; Hillel says to lean hands. The first [of each pair] was the nasi [head of the Sanhedrin] and the second [of each pair] was the av beit din [vice-head of the Sandhedrin].

(3) Beit Shammai says, they bring peace offerings [on Yom Tov] and do not lay their hands on them, but they do not bring burnt offerings. And Beit Hillel says, they bring both peace offerings and burnt offerings and lay their hands on them.

Source 5 This Mishna is the source for Chagigah 2:3. There are two distinct disputes embedded in this Mishna. First, is whether one should be bringing an Oleh on Yom Tov (everyone agrees a Shelamim may be brought as it is "Ochel Nefesh"). The second is whether one can perform Semicha on Yom Tov immediately prior to bringing his Korban or may he perform Semicha prior to Yom Tov. Embedded in the second dispute is whether or not Semicha must immediately precede the slaughtering of the Korban or may it be done earlier.

(ד) בית שמאי אומרים מביאין שלמים. ואין סומכין עליהן. אבל לא עולות. ובית הלל אומרים מביאין שלמים ועולות. וסומכין עליהם:

(4) Beit Shammai say: Shelamim [offerings whose various parts are consumed by their owners, by the priests, and by the fire on the altar] may be brought [on a festival], and one does not lean upon them [as one normally does when bringing a sacrifice], but not olot [offerings that are entirely burnt on the alter]. And Beit Hillel say: shelamim and olot may be brought [on a holiday], and one does lean upon them.

Source 6

The following sources, the Tosefta, Talmud Yerushalmi and Talmud Bavli expand and expound on the dispute over Semicha. The sources can be broken down into three distinct topics.

  1. The history of Halachik Disputes (Machlokes) --These are highlighted in yellow.
  2. The particular dispute between Beis Shammai and Beis Hillel over Semicha on Yom Tov--These are highlighted in blue
  3. A story of Hillel Hazaken and his attempt to bring a Korban Olah on Yom Tov and how a member of Beis Shammai helped establish the Halacha like Hillel. These are highlighted in purple.

The sources create an idyllic picture of Halachik history. At first, any time there was uncertainty or a difference of opinion over a particular Halacha, they would pose the question to the great 71-member Sanhedrin that sat inside the Beis HaMikdash. If someone had a tradition as to the proper rule (אם שמעו אמרו) they would accept the tradition. Otherwise, the august group would vote and determine the Halacha according to the majority. For reasons we will discuss, the one issue they could not resolve was the dispute over Semicha. Following Shammai and Hillel, their students no longer were capable of properly being instructed and from then on disputes multiplied.

As noted above, embedded within the Machlokes over Semicha on Yom Tov are two disputes. First, whether one may bring a Korban Olah on Yom Tov. According to Beis Shammai one cannot bring an Olah since it is wholly burnt rather than eaten, there is no purpose for such a Korban on Yom Tov. Beis Hillel permits a person to bring a Korban Olah on Yom Tov based on the principal that how can we concern ourselves with our food and not also be concerned with Hashem's. However, everyone agrees that you can bring a Shelamim on Yom Tov.

Separately, they argue whether or not one is permitted to perform Semicha on Yom Tov itself (whether for the Korban Olah according to Beis Hillel and the Shelamim according to everyone). According to Beis Shammai, you are permitted to do Semicha prior to bringing the Korban; consequently, he does not permit a person to violate the Rabbinic prohibition on using an animal on Yom Tov. According to Beis Hillel, however, one can only perform Semicha at the time of bringing the Korban and cannot do so earlier. When pitting the obligation to perform Semicha against the Rabbinic prohibition on using animals on Yom Tov, he allows Semicha to be performed.

Taking a step back, on a very practical level this dispute had meaningful consequences for the population. According to Beis Shammai a person who could not make the trek to the Beis HaMikdash (whether for the Festivals or any other time) could still send Korbonos and participate in ritual life since he could perform Semicha at home and send his Korban with a Shaliach. Whereas, according to Beis Hillel, this is Halachacily impermissible, and such a person would not be able to participate in the Temple ritual.

According to the sources, both disputes were eventually resolved. The sources vary slightly but the major details remain the same. The Talmud Yerushalmi's version is the most dramatic retelling. Briefly, Hillel once arrived at the Beis HaMikdash on Yom Tov prepared to bring a Korban Olah. Shammai's students quickly surround him (in an effort to prevent an Olah from being brought) and Hillel resorts to obfuscating the gender of the animal and pretends it is a female (which cannot be used for an Olah) and that he is bringing a Shelamim. Shammai's students invariably decide it's time to bring an end to the dispute by bringing the matter to a vote.

However, one student, Bava ben Butah knew that the Halachah was like Beis Hillel. According to the Yerushalmi's retelling, Bava was inspired/prompted by the reality of the fact that under Beis Shammai's paradigm the Beis HaMikdash was empty on Yom Tov. Rather than teeming with people it was desolate. Perhaps as a result of not being able to perform Semicha--while not absolutely required, it was very much a part of the Korban process for people--people refrained from bringing any Korbnos (including Shelamim) on Yom Tov. Preferring to wait until Chol HaMoed or after Shavuous when they could bring the Korban in the preferred manner.

To remedy the situation Bava went out and brought 3,000 animals to the Beis HaMikdash and urged the population to come and bring them--including allowing them to perform Semicha. And with that display he established the Halacha like Beis Hillel. Presumably as to both permitting Olos on Yom Tov and allowing Semicha to be performed at the same time. [One interesting note is whether the allowance of Semicha was only according to Hillel's rule that it must be performed immediately prior to slaughtering the animal or was it even according to Shammai who allowed you to perform Semicha earlier if need be. In other words, did they change the requirement for Semicha or did they dispense with the Rabbinic prohibition on using animals even when not directly conflicting with Semicha].

[My read of the sources suggest that Shammai's students were more concerned over an Olah being brought than whether or not Hillel was going to perform Semicha. The former would impugn the Beis HaMikdash as a whole (i.e., by having to be burnt on the Mizbeach) whereas, Hillel's desire to perform Semicha was a personal choice. However, all of the Bava ben Butah sources have him exhorting the population to come and bring Korbonos and to perform Semicha. This suggests that he was concerned with both issues. This then requires an explanation why the next statement in each of these sources is about a student of Hillel's bringing a Korban and performing Semicha who is stopped by a student of Shammai's demanding the former not perform Semicha. Hillel's student shuts down the objection with seemingly positive results. (I.e., establishing that Semicha can be performed on Yom Tov). While it may simply be a secondary form of support it does seem like it is meant to establish the Semicha rule. See Lieberman, Tosephta Kepshuta, Moed, pp 1200, n. 42 suggesting that Shammai and Hillel only disputed Semicha, it was their students who added the dispute of Korbnei Olah on Yom Tov.]

... And do Beit Shammai hold that obligatory peace-offerings do not require placing of hands on the head of the animal? But isn’t it taught in a baraita: Rabbi Yosei said: Beit Shammai and Beit Hillel did not disagree with regard to the placing of hands itself that it is required in the case of obligatory peace-offerings. With regard to what, then, did they disagree? They disagreed with regard to the halakha that states that immediately following placing hands on the head of an offering is its slaughter. As Beit Shammai say: It is not necessary to be particular in this regard, and the ceremony of placing hands on the animal’s head may be performed even on the eve of the Festival, long before the animal is slaughtered. And Beit Hillel say: It is necessary, and therefore one who brings an offering on a Festival must place his hands on the animal’s head on the Festival itself. The Gemara answers: The tanna of the mishna said what he said in accordance with the opinion of this tanna, as it is taught in a different baraita: Rabbi Yosei, son of Rabbi Yehuda, said: Beit Shammai and Beit Hillel did not disagree with regard to the halakha that immediately following placing hands on the head of an offering is its slaughter, that it is necessary. With regard to what, then, did they disagree? They disagreed with regard to the placing of hands itself on the head of obligatory peace-offerings. Beit Shammai say: It is not necessary, and Beit Hillel say: It is necessary. § The Gemara returns to the basic dispute between Beit Shammai and Beit Hillel.

The Sages taught in a baraita: There was an incident involving Hillel the Elder, who brought his burnt-offering to the Temple courtyard in order to place his hands on the animal’s head on a Festival. The students of Shammai the Elder gathered around him and said to him: What is the nature of this animal that you are bringing? Hillel, being humble and meek, did not want to quarrel with them in the Temple and therefore concealed the truth from them for the sake of peace. He said to them: It is a female, and I have brought it as a peace-offering, as burnt-offerings are always male. He swung its tail for them so that they would not be able to properly discern whether the animal was male or female, and they departed. On that day, when the incident became known, suggesting that even Hillel had accepted Shammai’s view, Beit Shammai gained the upper hand over Beit Hillel, and they sought to establish the halakha in this regard in accordance with their opinion. But a certain Elder of the disciples of Shammai the Elder was there, and Bava ben Buta was his name, who knew that the halakha is in accordance with the opinion of Beit Hillel in this matter. And he sent for and brought all the high-quality sheep of Kedar that were in Jerusalem, and he stood them in the Temple courtyard and said: Anyone who wishes to place his hands on the head of an animal should come and place his hands there. And on that day Beit Hillel gained the upper hand over Beit Shammai, and they established the halakha in this case in accordance with their opinion, and there was no one there who disputed the matter in any way.

And some time later there was another incident involving a certain disciple from among the disciples of Beit Hillel who brought his burnt-offering to the Temple courtyard in order to place his hands on the animal’s head on a Festival. A certain disciple from among the disciples of Beit Shammai found him and said to him: What is this placing of hands? Why do you place your hands on the animal’s head and thereby violate the statement of Beit Shammai? He said to him: What is this silence? Why do you not stay silent, as the halakha was not established in accordance with their opinion? He silenced him with a rebuke, and he, Beit Shammai’s disciple, departed quietly.

Source 7 The Gemara derives from the fact that there was even a dispute whether one can perform Semicha on Yom Tov that Semicha requires you to press and lean down on the animal with all your weight. Something that is not obvious from the Mishna. Second, we see that while women were not obligated in performing Semicha, they still desired to do so. The Semicha process was comforting in its own way perhaps by allowing a person to fully appreciate the magnitude of what was about to take place.

....אמר רמי בר חמא שמע מינה סמיכה בכל כחו בעינן דאי ס"ד לא בעינן בכל כחו מאי קא עביד ליסמוך מיתיבי (ויקרא א, ב) דבר אל בני ישראל וסמך בני ישראל סומכין ואין בנות ישראל סומכות רבי יוסי ור' (ישמעאל) [שמעון] אומרים בנות ישראל סומכות רשות אמר רבי יוסי סח לי אבא אלעזר פעם אחת היה לנו עגל של זבחי שלמים והביאנוהו לעזרת נשים וסמכו עליו נשים לא מפני שסמיכה בנשים אלא כדי לעשות נחת רוח לנשים ואי ס"ד סמיכה בכל כחו בעינן משום נחת רוח דנשים עבדינן עבודה בקדשים אלא לאו ש"מ לא בעינן בכל כחו לעולם אימא לך בעינן בכל כחו דאמר להו אקפו ידייכו אי הכי לא מפני שסמיכה בנשים תיפוק ליה דאינה לסמיכה כלל א"ר אמי חדא ועוד קאמר חדא דליתא לסמיכה כלל ועוד כדי לעשות נחת רוח לנשים אמר רב פפא שמע מינה צדדין אסורין דאי ס"ד צדדין מותרין לסמוך לצדדין אלא לאו שמע מינה צדדין אסורין

....Rami bar Ḥama said: You can learn from here, from this dispute, that the mitzva of placing hands requires not only placing one’s hands on the animal’s head, but we also require that one places his hands with all his strength. For if it enters your mind that we do not require all his strength, what prohibition does one violate by placing his hands? Let him place them on a Festival as well, as this does not resemble a prohibited action at all. The Gemara raises an objection to this from a baraita: “Speak to the children of [benei] Israel” (Leviticus 1:2). The word benei literally means: Sons of. And it states nearby: “And he shall place his hand on the head of the burnt-offering” (Leviticus 1:4), from which we learn that the sons of Israel place their hands, but the daughters of Israel do not place them. Rabbi Yosei and Rabbi Yishmael say: It is optional for the daughters of Israel to place their hands. They may place their hands if they so choose, although they are not obligated to do so. Rabbi Yosei said: The Sage Abba Elazar related to me the following incident: On one occasion, we had a calf for a peace-offering, and we brought it to the Women’s Courtyard, and women placed their hands on it. We did this not because there is an obligation of placing hands in the case of women, but in order to please the women, by allowing them to sacrifice an offering, in all of its particulars, as men do. Now, if it enters your mind that we require placing hands with all one’s strength, would we perform work with consecrated offerings in order to please the women? Placing one’s hands forcefully on an animal is considered performing work with it, and if one does it without being obligated to do so, he has thereby performed work with an offering. Rather, isn’t it correct to conclude from this that we do not require placing hands with all one’s strength? The Gemara rejects this: Actually, I could say to you that we do require placing hands with all one’s strength, but here they allowed women to place their hands by saying to them: Ease your hands and do not press forcefully, so that their hand placing should not constitute work. The Gemara retorts: If so, then the reason formulated as: Not because there is an obligation to place hands in the case of women, is irrelevant to this law. Let him derive the permission for women to do so from the reason that it is not considered placing hands at all. If placing hands must be performed with all one’s strength, this action the women are performing does not constitute placing hands. Rabbi Ami said: He stated one reason and another. One reason is that it is not considered placing hands at all, as it is not performed with all of one’s strength; and another reason is that they allowed it in order to please the women. Rav Pappa said: Learn from this that anything upon which one may not place objects or upon which one may not sit on Shabbat, its sides are likewise prohibited, for if it enters your mind to say that the sides are permitted, they could have told the women to place their hands on the sides, i.e., on the head of the animal rather than on its back, as the head of the animal is considered as if it were one of its sides. Rather, must one not conclude from this that the sides are prohibited?

Source 8

All of the above discussion assumes (as does the Talmud and all traditional Meforshim) that the Zugos were arguing whether or not Semicha on a Korban was permitted on Yom Tov. While it's clear what Beis Shammai and Beis Hillel were arguing over, it's not 100% clear that that is what the Zugos were arguing about. While the Mishna uses the terminology לסמוך ושלא לסמוך , nonetheless, it's not exactly the same. Among the Scholars, there has been much discussion as to the nature of the dispute. While many agree with the Gemara's conclusion, others have tried to find suitable substitutes. What follows is a brief recap.

Guiding the discussions are observations and questions like:

  • Why would Beis Shammai disrupt the bringing of Korbonos over a Shevus of leaning on an animal?
  • the juxtaposition of the two Mishnayos in Chagigah.
  • What was it about this dispute that could not be resolved over so many generations?
  • Why is there a need for a separate dispute by Beis Shammai and Beis Hillel?
  • The Tosefta says איזו היא סמיכה שנחלקו עליה regarding Beis Shammai and Beis Hillel and if they are the same as the Zugos why the limiting nature of the question?

Reliance and the Authority of the Chachomim and Tradition: According to Solomon Zeitlin, the subject of the Zugos's dispute is not over physical Semicha on an animal, rather it is over the reliance on and the authority of the Chahcomim. In other words, how much to be "סומך" on the Chachomim's traditions and innovations in Halacha. He attempts to prove this dispute transcended all five generations of Zugos by identifying identifying Halachos each of them said and showing how they can be attributed to their views of how much or, if at all, to rely on the changing traditions of the Chachomim.particular statements of Halachos each of them said and showing how they can be attributed t o their views over reliance on the Chachomim. One cogent point he makes is that according to his understanding, we can add Mishna 2:2 to the prior set of Mishanyos dealing with the types and nature of Torah Shel Ba'al Peh, i.e., this Mishna concludes that grouping.

Laying of hands at time of Ordination: Some scholars have suggested that the preserved dispute is whether or not rabbinic ordination required the laying of the hands on the student's head. The ambiguity can be seen in the differing interpretations given by traditional commentators to the opening line of Mishna 1:3 in Sanhedrin. There is says, סְמִיכַת זְקֵנִים וַעֲרִיפַת עֶגְלָה, בִּשְׁלֹשָׁה, דִּבְרֵי רַבִּי שִׁמְעוֹן. Many of the commentators, taking their que from the Gemara and the context of the Mishna, understand the Mishna to be referring to Semicha on a Korban. Specifically, the special Korban brought by the Court when a wrongful ruling is relied and acted upon by the majority of the people. The Rambam, on the other hand, interprets our Mishna as referring to Rabbinic Ordination. Others, including the R"AV and Yachin suggest that the Mishna is referring to both scenarios. Either way, it highlights the ambiguity of the term Samach. See sources and rebuttal at Lawrence A. Hoffman, The Origins of Ordination, in Rabbinic Authority, Papers Presented before he Ninety-First Annual Convention of the Central Conference of American Rabbis ("CCAR"), Vol. XC, Part Two, Ed., Elliot L.

Traditionalist Views: Even among those who accept the traditional interpretation that the Zugos' controversy is over Semicha on an animal, they nonetheless dispute the contours and the particulars of the dispute.

  • Zecharias Frankel, Darchei HaMishna, Breslau pp. 43-44 suggests that while the dispute may have started over the appropriateness of Semicha on Yom Tov, as noted above, underlying that that dispute was how you viewed the core obligation of Semicha. Was it simply the preferred way to bring a Korban or was it obligatory? Allowing Semicha on Yom Tov meant it was likely obligatory and if obligatory, that meant those who lived far from the Beis HaMikdash could not send Korbonos. [per the Gemarah eve according to Beis Shammai they could perform Semicha the day before--but perhaps he does not read that into the Mishna.] According to Frankel, this dispute proved wider and enveloped Korbonos throughout the year. The Chachomim, rather than resolving the issue, allowed it to remain an open question thus allowing each individual to choose whether to come and perform Semicha or send his Korban to the Beis HaMikdash without performing Semicha.
  • Isaac Hersh Weiss, Dor Dor V'Dorshav, Vol. 1, pp 98, takes exception to Frankel's limitation and argues that the controversy was over Semicha on Yom Tov and the reason it lasted so long was that it was, in part, the prototype for the developing disputes among the Peirushim and Tziddukim. At its core, the Machlokes whether to perform Semicha in the face of a Rabbinic prohibition. Pitting the Biblical imperative against the Rabbinic injunction.
  • Yaakov Halevy, Otzar Nechmad, Vol. 3, Isaac Blumenfeld editor, Wien, 1860, pp. 27-40, takes this to the extreme, identifying the dispute in our Mishna as a vestige of a dispute with the Essene's. According to Blumenfeld, the Essene's viewed themselves as always being ritually impure, preventing them from approaching the Beis HaMikdash and bringing a Korban. Recognizing, however, that to completely disengage from the Temple ritual would mean cutting themselves off from the entirety of the Jewish nation, they needed to figure out a way to still bring Korbonos. This was not only an issue for the Festivals, but for everyday life. The major impediment was the obligation to perform Semicha immediately prior to the slaughtering of the animal--an impossibility for the Essenes. However, if they could reinterpret the obligation to one of discretionary conduct, they could then send their Korbonos to the Beis HaMikdash. This line of thinking is rather extreme and also is problematic as he takes the liberty of identifying many of the Tanaim in our Misha as being Essenes.
  • E. E. Halevy, Tarbiz, Teves 5719, pp. 154-157: views the controversy from a sociological perspective. [Some of this is incorporated above in my explanation of the sources]. It is clear that Semicha was an integral part of the Korban process. It was the most participatory aspect of the Korban and, therefore, the most meaningful. In the absence of being able to perform Semicha the people stopped bringing Korbonos, hence the desolation of the Beis HaMikdash even though everyone agreed they could bring Shelamim. He goes one step further and suggests that at its core, the Machlokes between the Zugos and Beis Shammai and Beis Hillel was over the character of the Beis HaMikdash during the Festivals. Would it have a somber and staid feel in line with the auspicious nature of the day or would it have a more carnivalesque feel with multitudes streaming in through the gates with their Korbonos, creating a ruckus and much joyous atmosphere. Those who wanted the former, understood that limiting the performance of Semicha would have the natural effect of drastically limiting the quantum and quantity of Korbonos. In other words, the prohibition or permissibility of Semicha was a proxy for their perception as to and over the nature of the Beis HaMikdash on the Yomim Tovim.
