תנורו של עכנאי - המפץ הגדול

And these are they which are unclean unto you among the swarming things that swarm upon the earth: the weasel, and the mouse, and the great lizard after its kinds, and the gecko, and the land-crocodile, and the lizard, and the sand-lizard, and the chameleon. These are they which are unclean to you among all that swarm; whosoever doth touch them, when they are dead, shall be unclean until the even. And upon whatsoever any of them, when they are dead, doth fall, it shall be unclean; whether it be any vessel of wood, or raiment, or skin, or sack, whatsoever vessel it be, wherewith any work is done, it must be put into water, and it shall be unclean until the even; then shall it be clean. And every earthen vessel whereinto any of them falleth, whatsoever is in it shall be unclean, and it ye shall break. All food therein which may be eaten, that on which water cometh, shall be unclean; and all drink in every such vessel that may be drunk shall be unclean. And every thing whereupon any part of their carcass falleth shall be unclean; whether oven, or range for pots, it shall be broken in pieces; they are unclean, and shall be unclean unto you.

If he cut the oven up into rings, and then he put sand between each pair of rings, Rabbi Eliezer says: it is clean. But the sages say: it is unclean. This is the oven of Akhnai. As regards Arabian vats, which are holes dug in the ground and plastered with clay, if the plastering can stand of itself it is susceptible to impurity; Otherwise it is not susceptible. This is the oven of Ben Dinai.

§ Apropos the topic of verbal mistreatment, we learned in a mishna there (Kelim 5:10): If one cut an earthenware oven widthwise into segments, and placed sand between each and every segment, Rabbi Eliezer deems it ritually pure. Because of the sand, its legal status is not that of a complete vessel, and therefore it is not susceptible to ritual impurity. And the Rabbis deem it ritually impure, as it is functionally a complete oven. 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.

They [each] said three things: Rabbi Eliezer said: Let the honor of your friend be as dear to you as your own; And be not easily provoked to anger; And repent one day before your death. And [he also said:] warm yourself before the fire of the wise, but beware of being singed by their glowing coals, for their bite is the bite of a fox, and their sting is the sting of a scorpion, and their hiss is the hiss of a serpent, and all their words are like coals of fire.
