It was taught: On that day that they removed Rabban Gamliel from his position and appointed Rabbi Elazar ben Azarya in his place, there was also a fundamental change in the general approach of the study hall as they dismissed the guard at the door and permission was granted to the students to enter. Instead of Rabban Gamliel’s selective approach that asserted that the students must be screened before accepting them into the study hall, the new approach asserted that anyone who seeks to study should be given opportunity to do so. As Rabban Gamliel would proclaim and say: Any student whose inside, his thoughts and feelings, are not like his outside, i.e., his conduct and his character traits are lacking, will not enter the study hall. The Gemara relates: On that day several benches were added to the study hall to accommodate the numerous students. Rabbi Yoḥanan said: Abba Yosef ben Dostai and the Rabbis disputed this matter. One said: Four hundred benches were added to the study hall. And one said: Seven hundred benches were added to the study hall. When he saw the tremendous growth in the number of students, Rabban Gamliel was disheartened. He said: Perhaps, Heaven forbid, I prevented Israel from engaging in Torah study. They showed him in his dream white jugs filled with ashes alluding to the fact that the additional students were worthless idlers. The Gemara comments: That is not the case, but that dream was shown to him to ease his mind so that he would not feel bad. It was taught: There is a tradition that tractate Eduyyot was taught that day. And everywhere in the Mishna or in a baraita that they say: On that day, it is referring to that day. There was no halakha whose ruling was pending in the study hall that they did not explain and arrive at a practical halakhic conclusion. And even Rabban Gamliel did not avoid the study hall for even one moment, as he held no grudge against those who removed him from office and he participated in the halakhic discourse in the study hall as one of the Sages. As we learned in a mishna: On that day, Yehuda, the Ammonite convert, came before the students in the study hall and he said to them: What is my legal status in terms of entering into the congregation of Israel, i.e., to marry a Jewish woman? Rabban Gamliel said to him: You are forbidden to enter into the congregation. Rabbi Yehoshua said to him: You are permitted to enter into the congregation. Rabban Gamliel said to Rabbi Yehoshua: Wasn’t it already stated: “An Ammonite and a Moabite shall not enter into the congregation of the Lord; even to the tenth generation shall none of them enter into the congregation of the Lord forever” (Deuteronomy 23:4)? How can you permit him to enter the congregation? Rabbi Yehoshua said to Rabban Gamliel: Do Ammon and Moab reside in their place? Sennacherib already came and, through his policy of population transfer, scrambled all the nations and settled other nations in place of Ammon. Consequently, the current residents of Ammon and Moab are not ethnic Ammonites and Moabites, as it is stated in reference to Sennacherib: “I have removed the bounds of the peoples, and have robbed their treasures, and have brought down as one mighty the inhabitants” (Isaiah 10:13). And although it is conceivable that this particular convert is an ethnic Ammonite, nevertheless, there is no need for concern due to the halakhic principle: Anything that parts from a group parts from the majority, and the assumption is that he is from the majority of nations whose members are permitted to enter the congregation. Rabban Gamliel said to Rabbi Yehoshua: But wasn’t it already stated: “But afterward I will bring back the captivity of the children of Ammon, says the Lord” (Jeremiah 49:6) and they have already returned to their land? Therefore, he is an ethnic Ammonite and he may not convert. Rabbi Yehoshua said to Rabban Gamliel: That is no proof. Wasn’t it already stated in another prophecy: “And I will turn the captivity of My people Israel and they shall build the waste cities, and inhabit them; and they shall plant vineyards, and drink the wine thereof; they shall also make gardens, and eat the fruit of them” (Amos 9:14), and they have not yet returned? In rendering the ruling, only proven facts may be taken into consideration. They immediately permitted him to enter the congregation. This proves that Rabban Gamliel did not absent himself from the study hall that day and participated in the halakhic discourse. Rabban Gamliel said to himself: Since this is the situation, that the people are following Rabbi Yehoshua, apparently he was right. Therefore, it would be appropriate for me to go and appease Rabbi Yehoshua. When he reached Rabbi Yehoshua’s house, he saw that the walls of his house were black. Rabban Gamliel said to Rabbi Yehoshua in wonderment: From the walls of your house it is apparent that you are a blacksmith, as until then he had no idea that Rabbi Yehoshua was forced to engage in that arduous trade in order to make a living. Rabbi Yehoshua said to him: Woe unto a generation that you are its leader as you are unaware of the difficulties of Torah scholars, how they make a living and how they feed themselves. Rabban Gamliel said to him: I insulted you, forgive me. Rabbi Yehoshua paid him no attention and did not forgive him. He asked him again: Do it in deference to my father, Rabban Shimon ben Gamliel, who was one of the leaders of Israel at the time of the destruction of the Temple. He was appeased. Now that Rabbi Yehoshua was no longer offended, it was only natural that Rabban Gamliel would be restored to his position. They said: Who will go and inform the Sages? Apparently, they were not eager to carry out the mission that would undo the previous actions and remove Rabbi Elazar ben Azarya from his position as Nasi. This launderer said to them: I will go. Rabbi Yehoshua sent to the Sages to the study hall: The one who wears the uniform will continue to wear the uniform, the original Nasi will remain in his position so that the one who did not wear the uniform will not say to the one who wears the uniform, remove your uniform and I will wear it. Apparently, the Sages believed that this emissary was dispatched at the initiative of Rabban Gamliel and they ignored him. Rabbi Akiva said to the Sages: Lock the gates so that Rabban Gamliel’s servants will not come and disturb the Sages. When he heard what happened, Rabbi Yehoshua said: It is best if I go to them. He came and knocked on the door. He said to them with a slight variation: One who sprinkles pure water on those who are ritually impure, son of one who sprinkles water shall continue to sprinkle water. And it is inappropriate that he who is neither one who sprinkles nor son of one who sprinkles will say to one who sprinkles son of one who sprinkles: Your water is cave water and not the running water required to purify one exposed to ritual impurity imparted by a corpse and your ashes are burnt ashes and not the ashes of a red heifer. Rabbi Akiva said to him: Rabbi Yehoshua, have you been appeased? Everything we did was to defend your honor. If you have forgiven him, none of us is opposed. Early tomorrow you and I will go to Rabban Gamliel’s doorway and offer to restore him to his position as Nasi. The question arose what to do with Rabbi Elazar ben Azarya? They said: What shall we do? Remove him from his position. That is inappropriate as we learned a halakha through tradition: One elevates to a higher level of sanctity and does not downgrade. Therefore, one who was the Nasi of the Sanhedrin cannot be demoted. Let one Sage lecture one week and the other Sage one week, they will come to be jealous one of another, as they will be forced to appoint one as the acting head of the Sanhedrin. Rather, Rabban Gamliel will lecture three weeks and Rabbi Elazar ben Azarya will lecture as head of the yeshiva one week. That arrangement was adopted and that is the explanation of the exchange in tractate Ḥagiga: Whose week was it? It was the week of Rabbi Elazar ben Azarya. One final detail: That student who asked the original question that sparked this entire incident was Rabbi Shimon ben Yoḥai.
