אבות א, א - חוק חינוך חובה נוסח חז"ל

(1) Moshe received the Torah from Sinai and transmitted it to Yehoshua, and Yehoshua to the Elders, and the Elders to the Prophets, and the Prophets transmitted it to the Men of the Great Assembly. They said three things: Be deliberate in judgment, raise up many disciples and make a fence for the Torah.

(1) Moshe received the Torah from Sinai: I say: Since this tractate is not founded on the exegesis of commandments from among the Torah’s commandments, like the rest of the tractates which are in the Mishna, but is rather wholly morals and principles, and whereas the sages of the (other) nations of the world have also composed books according to the fabrication of their hearts, concerning moral paths, how a person should behave with his fellow; therefore, in this tractate the tanna began "Moshe received Torah from Sinai," to tell you that the principles and morals which are in this tractate were not fabricated by the hearts of the Mishna’s sages; rather, they too were stated at Sinai.

(5) and the Elders to the Prophets, and the Prophets transmitted it to the Men of the Great Assembly: And that is Ezra and his group. And [some of] the prophets of the Second Temple were in that group...And the men of the Great Assembly transmitted it to the men of their generation. And the sages [transmitted it] to their children after them in each and every generation. And the transmission was from one sage to another, until all of the sages of Israel gathered and a suggestion was given from all of their mouths to write down the oral Torah. And [so] they wrote and sealed the Talmud, and afterwards nothing was added to it and nothing was taken away from it. And that generation also transmitted it to the Geonim and the transmission was from one Gaon to another, one rabbi to another - until this day.

(6) "Be discerning in judgment": Where if a case comes before you one, two or three (times), do not say "This case already came before me, and (I ruled) a second and a third time." Rather, "Be discerning," which is to say deliberate before you decide the case.

(7) "stand up many students": (This is meant) to exclude (the words of) Rabban Gamliel, who said "Any student whose exterior is not like his interior shall not enter the Beit Midrash (Berakhot 28a)." We derive from this that we teach Torah to every person; there is no need to inquire after him. [This is the case] so long as it not be known from from his way that his actions are corrupt or that he has a bad reputation...

(8) "and establish a fence for the Torah": A hedge, in order that he not come into contact with a Torah prohibition, such as second degree sexual relationships or rabbinic fences to protect the Shabbat as is written (Lev. 18:30), “You shall keep my guard;” [meaning,] ‘Make a safeguard for my safeguard.’

...Rav Yehuda says that Rav says: Truly, that man is remembered for the good, and his name is Yehoshua ben Gamla. If not for him the Torah would have been forgotten from the Jewish people. Initially, whoever had a father would have his father teach him Torah, and whoever did not have a father would not learn Torah at all. The Gemara explains: What verse did they interpret homiletically that allowed them to conduct themselves in this manner? They interpreted the verse that states: “And you shall teach them [otam] to your sons” (Deuteronomy 11:19), to mean: And you yourselves [atem] shall teach, i.e., you fathers shall teach your sons. When the Sages saw that not everyone was capable of teaching their children and Torah study was declining, they instituted an ordinance that teachers of children should be established in Jerusalem. The Gemara explains: What verse did they interpret homiletically that enabled them to do this? They interpreted the verse: “For Torah emerges from Zion” (Isaiah 2:3). But still, whoever had a father, his father ascended with him to Jerusalem and had him taught, but whoever did not have a father, he did not ascend and learn. Therefore, the Sages instituted an ordinance that teachers of children should be established in one city in each and every region [pelekh]. And they brought the students in at the age of sixteen and at the age of seventeen. But as the students were old and had not yet had any formal education, a student whose teacher grew angry at him would rebel against him and leave. It was impossible to hold the youths there against their will. This state of affairs continued until Yehoshua ben Gamla came and instituted an ordinance that teachers of children should be established in each and every province and in each and every town, and they would bring the children in to learn at the age of six and at the age of seven.

(5) Twenty-five children should be the maximum number for one teacher to instruct. If there be more than twenty-five children but not exceeding forty, an assistant should be appointed to help him in giving them instructions; if the number exceeds forty children, two teachers should be appointed.⁵Baba Batra, 21b. C.

...School children should not be rendered idle even for the sake of building the Holy Temple.²Baba Batra, 21b; Ketubot, 50a; Nedarim, 37a. C. See Ta’anit 3b. G.

Rav Hamnuna said: Jerusalem was destroyed only because schoolchildren there were interrupted from studying Torah...
