b) Wise and wealthy, and wealthy in Ezra and Cohen. [And when they transferred Rabban Gamliel of Yavneh, they appointed him as Nasi at the age of eighteen, and a miracle occurred for him, and they added to him eighteen rows of honor. And he taught that a person should always engage in Torah, even not for its own sake, so that he may come to engage for its own sake, and ten benches were added, and there are those who say, come and see the benches, Berakhot (28).
And it is written in the genealogy [in Seder HaDoros] in the name of the Jerusalem Talmud, in the chapter of Tamid that was slaughtered, that he was thirteen years old, and it is mentioned only in Berakhot, in the chapter of the Morning Prayer, at the end of Mishnah 1, and in Ta'anit, chapter 4, at the end of Halacha 1. He was sixteen years old, and his head was filled with white hair, and Rabbi Akiva was sitting and grieving and said, not that he is a man of Torah more than me, but that he is a descendant of great ones more than me.
Fortunate is the person who has merited to have ancestors like his; fortunate is the person who has a peg to hang onto, and what was his peg? He was the tenth generation from Ezra. And how many benches were there? That is to say, benches of Torah scholars, aside from those standing behind the fence, as it is written, one hundred outside, etc.
And when they agreed to seat Rabban Gamliel, Rabbi Eliezer ben Azariah arose with them at the entrance of Rabban Gamliel, nevertheless, they did not diminish his greatness, but appointed him as Av Beit Din.
Thus far the text. And it is written in Yefeh Mar'eh, in the chapter of the Morning Prayer, in the gloss, section 8, that in the Babylonian Talmud, in the chapter of the Many, Rabbi Yehoshua was the Av Beit Din of Rabban Gamliel.
Therefore, it is understood that Rabbi Eliezer ben Azariah was not Av Beit Din, but after they restored Rabban Gamliel to the Nasi position, Rabban Gamliel taught for two Shabbatot, and Rabbi Eliezer ben Azariah taught for one Shabbat. (And in Shabbat (22b) it is written that Rabbi Yochanan was with Rabban Gamliel for forty years). And it is written in the genealogy there, and we do not leave the simple meaning, and he was more than seventy years old, as he said, behold, I am like a seventy-year-old.
And the Jerusalem Talmud did not speak of this as being like a seventy-year-old.
Thus far the text. I do not understand, for if it is as it seems, that he was seventy years old, why did he say like a seventy-year-old? And perhaps indeed when he was appointed as Nasi, he was eighteen or sixteen, but when he taught about the Exodus from Egypt at night, he was seventy, and he did not merit that they should agree with him until Ben Zoma taught. And in the Jerusalem Talmud, in the first chapter of Berakhot, it is said, behold, I am like a seventy-year-old, even though he entered into greatness, he lived many days.
Thus far the text. And Yefeh Mar'eh wrote in section 19 that this contradicts the Babylonian Talmud, which said that on the day they appointed him as Nasi, they added to him eighteen rows of honor, on that he said, behold, I am like a seventy-year-old]:
