Makhloket in Jewish Tradition

(17) Every disagreement that is for [the sake of] heaven, it is destined to endure. But if it is not for the sake of heaven it, is not destined to endure.

What is an example of a disagreement for the sake of heaven? The disagreement of Hillel and Shammai.

And what is one not for the sake of heaven? The disagreement of Korach and all of his congregation.

Rabbi Abba said that Shmuel said: For three years Beit Shammai and Beit Hillel disagreed. These said: The halakha is in accordance with our opinion, and these said: The halakha is in accordance with our opinion. Ultimately, a Divine Voice emerged and proclaimed: Both these and those (eilu v'eilu) are the words of the living God. However, the halakha is in accordance with Beit Hillel.

Since both these and those are the words of the living God, why were Beit Hillel privileged to have the halakha established in accordance with their opinion? They were agreeable and forbearing, they would teach both their own statements and the statements of Beit Shammai. Moreover, they prioritized the statements of Beit Shammai to their own statements.

(4) Beit Shammai permit the rivals to the brothers [for marriage], but Beit Hillel forbid [them]. [If these women] had performed Chalitzah Beit Shammai disqualify them from [subsequently marrying] priests, but Beit Hillel allow them [to do so]. [If these women] had undergone Yibum, Beit Shammai permit them [to subsequently marry priests], but Beit Hillel disqualify them [from such a union]. Even though these [one school] prohibit and these [the other school] permit, these disqualify and these allow, Beit Shammai did not refrain from marrying women from Beit Hillel, nor did Beit Hillel [refrain from marrying women] from Beit Shammai. [With regard to] purity and impurity where these ruled [a matter] pure and these ruled [it] impure, they did not refrain from using [utensils] the other deemed pure.

"They did not prevent" -- Even though the children of a rival who underwent yibum according to Beit Shammai were mamzerim ​according to Beit Hillel (since they would be forbidden as a sister-in-law, which is punishable by karet; and children of a forbidden relationship punishable by karet are mamzerim). Even so, Beit Hillel did not prevent themselves from marrying women from Beit Shammai, for they would let them know which women were children of rival wives [in yibbum relationships] and they would stay away from them.

Although Beit Shammai and Beit Hillel disagreed (on many critical issues) ... nevertheless .. they behaved with love and friendship toward one another, as it says in Zecharia, "TRUTH and PEACE they loved."

“Those that are composed in collections [ba’alei asufot]”: These are Torah scholars who sit in many groups [asupot] and engage in Torah study. There are often debates among these groups, as some of these Sages render an object or person ritually impure and these render it pure; these prohibit an action and these permit it; these deem an item invalid and these deem it valid. Lest a person say: Now, how can I study Torah when it contains so many different opinions? The verse states that they are all “given from one shepherd.” One God gave them; one leader, i.e., Moses, said them from the mouth of the Master of all creation, Blessed be He, as it is written: “And God spoke all these words” (Exodus 20:1). The plural form “words” indicates that God transmitted all the interpretations of the Ten Commandments. Since the Sages invariably utilize the Torah itself or the statements of the prophets as the sources for their opinions, there is a certain unity to the study of Torah, despite the numerous explanations and applications.

And this is known as the oven of akhnai. The Gemara asks: What is the relevance of akhnai, a snake, in this context? Rav Yehuda said that Shmuel said: It is characterized in that manner due to the fact that the Rabbis surrounded it with their statements like this snake, which often forms a coil when at rest, and deemed it impure. The Sages taught: On that day, when they discussed this matter, Rabbi Eliezer answered all possible answers in the world to support his opinion, but the Rabbis did not accept his explanations from him.

After failing to convince the Rabbis logically, Rabbi Eliezer said to them: If the halakha is in accordance with my opinion, this carob tree will prove it. The carob tree was uprooted from its place one hundred cubits, and some say four hundred cubits. The Rabbis said to him: One does not cite halakhic proof from the carob tree.

Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the stream will prove it. The water in the stream turned backward and began flowing in the opposite direction. They said to him: One does not cite halakhic proof from a stream.

Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the walls of the study hall will prove it. The walls of the study hall leaned inward and began to fall. Rabbi Yehoshua scolded the walls and said to them: If Torah scholars are contending with each other in matters of halakha, what is the nature of your involvement in this dispute? The Gemara relates: The walls did not fall because of the deference due Rabbi Yehoshua, but they did not straighten because of the deference due Rabbi Eliezer, and they still remain leaning.

Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, Heaven will prove it. A Divine Voice emerged from Heaven and said: Why are you differing with Rabbi Eliezer, as the halakha is in accordance with his opinion in every place that he expresses an opinion? Rabbi Yehoshua stood on his feet and said: It is written: “It is not in heaven” (Deuteronomy 30:12). The Gemara asks: What is the relevance of the phrase “It is not in heaven” in this context? Rabbi Yirmeya says: Since the Torah was already given at Mount Sinai, we do not regard a Divine Voice, as You already wrote at Mount Sinai, in the Torah: “After a majority to incline” (Exodus 23:2). Since the majority of Rabbis disagreed with Rabbi Eliezer’s opinion, the halakha is not ruled in accordance with his opinion.

The Gemara relates: Years after, Rabbi Natan encountered Elijah the prophet and said to him: What did the Holy One, Blessed be He, do at that time, when Rabbi Yehoshua issued his declaration? Elijah said to him: The Holy One, Blessed be He, smiled and said: My children have triumphed over Me; My children have triumphed over Me.

The Sages said: On that day, the Sages brought all the ritually pure items deemed pure by the ruling of Rabbi Eliezer with regard to the oven and burned them in fire, and the Sages reached a consensus in his regard and ostracized him. And the Sages said: Who will go and inform him of his ostracism? Rabbi Akiva, his beloved disciple, said to them: I will go, lest an unseemly person go and inform him in a callous and offensive manner, and he would thereby destroy the entire world.

What did Rabbi Akiva do? He wore black and wrapped himself in black, as an expression of mourning and pain, and sat before Rabbi Eliezer at a distance of four cubits, which is the distance that one must maintain from an ostracized individual. Rabbi Eliezer said to him: Akiva, what is different about today from other days, that you comport yourself in this manner? Rabbi Akiva said to him: My teacher, it appears to me that your colleagues are distancing themselves from you. He employed euphemism, as actually they distanced Rabbi Eliezer from them. Rabbi Eliezer too, rent his garments and removed his shoes, as is the custom of an ostracized person, and he dropped from his seat and sat upon the ground.

The Gemara relates: His eyes shed tears, and as a result the entire world was afflicted: One-third of its olives were afflicted, and one-third of its wheat, and one-third of its barley. And some say that even dough kneaded in a woman’s hands spoiled. The Sages taught: There was great anger on that day, as any place that Rabbi Eliezer fixed his gaze was burned.

And even Rabban Gamliel, the Nasi of the Sanhedrin at Yavne, the head of the Sages who were responsible for the decision to ostracize Rabbi Eliezer, was coming on a boat at the time, and a large wave swelled over him and threatened to drown him. Rabban Gamliel said: It seems to me that this is only for the sake of Rabbi Eliezer ben Hyrcanus, as God punishes those who mistreat others. Rabban Gamliel stood on his feet and said: Master of the Universe, it is revealed and known before You that neither was it for my honor that I acted when ostracizing him, nor was it for the honor of the house of my father that I acted; rather, it was for Your honor, so that disputes will not proliferate in Israel. In response, the sea calmed from its raging.

The Gemara further relates: Imma Shalom, the wife of Rabbi Eliezer, was the sister of Rabban Gamliel. From that incident forward, she would not allow Rabbi Eliezer to lower his head and recite the taḥanun prayer, which includes supplication and entreaties. She feared that were her husband to bemoan his fate and pray at that moment, her brother would be punished. A certain day was around the day of the New Moon, and she inadvertently substituted a full thirty-day month for a deficient twenty-nine-day month, i.e., she thought that it was the New Moon, when one does not lower his head in supplication, but it was not. Some say that a pauper came and stood at the door, and she took bread out to him. The result was that she left her husband momentarily unsupervised. When she returned, she found him and saw that he had lowered his head in prayer.

She said to him: Arise, you already killed my brother. Meanwhile, the sound of a shofar emerged from the house of Rabban Gamliel to announce that the Nasi had died. Rabbi Eliezer said to her: From where did you know that your brother would die? She said to him: This is the tradition that I received from the house of the father of my father: All the gates of Heaven are apt to be locked, except for the gates of prayer for victims of verbal mistreatment.

R. Oshaya said: The scholars of the Land of Israel treat each other graciously when engaged in debates (Rashi [10th c. France] adds: [what does this mean?] look into the matter together, and this one corrects the other politely, and the law comes to light). However, the scholars of Babylon injure each other (Rashi: with strong and heated language) when debating.

(7) Seven things [apply] to a fool, and seven to a wise person. A wise person does not speak in front of someone who is greater than him in wisdom, and he does not interrupt his fellow, and he is not afraid to answer; he asks on topic, and he answers according to the law. He talks about the first thing first, and the last thing last. About that which he has never heard he says, "I never heard," and he admits to the truth. And the opposite of these [is true] for the fool.
