ת"ר מעשה ברבי יוחנן בן ברוקה ורבי אלעזר (בן) חסמא שהלכו להקביל פני ר' יהושע בפקיעין אמר להם מה חידוש היה בבית המדרש היום אמרו לו תלמידיך אנו ומימיך אנו שותין אמר להם אף על פי כן אי אפשר לבית המדרש בלא חידוש שבת של מי היתה שבת של ר' אלעזר בן עזריה היתה ובמה היתה הגדה היום אמרו לו בפרשת הקהל ומה דרש בה (דברים לא, יב) הקהל את העם האנשים והנשים והטף אם אנשים באים ללמוד נשים באות לשמוע טף למה באין כדי ליתן שכר למביאיהן אמר להם מרגלית טובה היתה בידכם ובקשתם לאבדה ממני
The Sages taught: There was an incident involving Rabbi Yoḥanan ben Beroka and Rabbi Elazar ben Ḥisma, when they went to greet Rabbi Yehoshua in Peki’in. Rabbi Yehoshua said to them: What novel idea was taught today in the study hall? They said to him: We are your students and we drink from your water, i.e., all of our Torah knowledge comes from you, and therefore how can we tell you something you have not already learned? He said to them: Even so, there cannot be a study hall without a novelty. He asked them: Whose week was it, i.e. who was the lecturer this week? They said to him: It was Rabbi Elazar ben Azarya’s week. He inquired: And on what subject was the lecture today? They said to him: He spoke about the portion of the mitzva of assembly. Rabbi Yehoshua persisted: And what verse did he interpret homiletically with regard to this mitzva? They said to him that Rabbi Elazar ben Azarya interpreted the following verse: “Assemble the people, the men and the women and the little ones” (Deuteronomy 31:12). This verse is puzzling: If men come to learn, and women, who might not understand, come at least to hear, why do the little ones come? They come in order for God to give a reward to those who bring them, i.e., God credits those who bring their children to the assembly. Rabbi Yehoshua said to them: This good pearl of wisdom was in your hands, and you tried to conceal it from me?
