אמר רבי דוסא בן הורכינס עדי שקר הן היאך מעידים על האשה שילדה ולמחר כריסה בין שיניה אמר לו רבי יהושע רואה אני את דבריך שלח לו ר"ג גוזרני עליך שתבא אצלי במקלך ובמעותיך ביוה"כ שחל להיות בחשבונך הלך ומצאו ר"ע מיצר אמר לו יש לי ללמוד שכל מה שעשה ר"ג עשוי שנאמר (ויקרא כג, ד) אלה מועדי ה' מקראי קדש אשר תקראו אתם בין בזמנן בין שלא בזמנן אין לי מועדות אלא אלו בא לו אצל ר' דוסא בן הורכינס אמר לו אם באין אנו לדון אחר בית דינו של ר"ג צריכין אנו לדון אחר כל בית דין ובית דין שעמד מימות משה ועד עכשיו שנאמר (שמות כד, ט) ויעל משה ואהרן נדב ואביהוא ושבעים מזקני ישראל ולמה לא נתפרשו שמותן של זקנים אלא ללמד שכל שלשה ושלשה שעמדו בית דין על ישראל הרי הוא כבית דינו של משה נטל מקלו ומעותיו בידו והלך ליבנה אצל ר"ג ביום שחל יוה"כ להיות בחשבונו עמד ר"ג ונשקו על ראשו אמר לו בוא בשלום רבי ותלמידי רבי בחכמה ותלמידי שקבלת את דברי:
Rabbi Dosa ben Horkinas disagreed and said: They are false witnesses; how can witnesses testify that a woman gave birth and the next day her belly is between her teeth, i.e., she is obviously still pregnant? If the new moon was already visible at its anticipated time, how could it not be seen a day later? Rabbi Yehoshua said to him: I see the logic of your statement; the New Moon must be established a day later. Upon hearing that Rabbi Yehoshua had challenged his ruling, Rabban Gamliel sent a message to him: I decree against you that you must appear before me with your staff and with your money on the day on which Yom Kippur occurs according to your calculation; according to my calculation, that day is the eleventh of Tishrei, the day after Yom Kippur. Rabbi Akiva went and found Rabbi Yehoshua distressed that the head of the Great Sanhedrin was forcing him to desecrate the day that he maintained was Yom Kippur. In an attempt to console him, Rabbi Akiva said to Rabbi Yehoshua: I can learn from a verse that everything that Rabban Gamliel did in sanctifying the month is done, i.e., it is valid. As it is stated: “These are the appointed seasons of the Lord, sacred convocations, which you shall proclaim in their season” (Leviticus 23:4). This verse indicates that whether you have proclaimed them at their proper time or whether you have declared them not at their proper time, I have only these Festivals as established by the representatives of the Jewish people. Rabbi Yehoshua then came to Rabbi Dosa ben Horkinas, who said to him: If we come to debate and question the rulings of the court of Rabban Gamliel, we must debate and question the rulings of every court that has stood from the days of Moses until now. As it is stated: “Then Moses went up, and Aaron, Nadav and Avihu, and seventy of the Elders of Israel” (Exodus 24:9). But why were the names of these seventy Elders not specified? Rather, this comes to teach that every set of three judges that stands as a court over the Jewish people has the same status as the court of Moses. Since it is not revealed who sat on that court, apparently it is enough that they were official judges in a Jewish court. When Rabbi Yehoshua heard that even Rabbi Dosa ben Horkinas maintained that they must submit to Rabban Gamliel’s decision, he took his staff and his money in his hand, and went to Yavne to Rabban Gamliel on the day on which Yom Kippur occurred according to his own calculation. Upon seeing him, Rabban Gamliel stood up and kissed him on his head. He said to him: Come in peace, my teacher and my student. You are my teacher in wisdom, as Rabbi Yehoshua was wiser than anyone else in his generation, and you are my student, as you accepted my statement, despite your disagreement.
הלך ר"ע (ומצאו) מיצר כו': איבעיא להו מי מיצר ר"ע מיצר או רבי יהושע מיצר ת"ש דתניא הלך ר"ע ומצאו לרבי יהושע כשהוא מיצר אמר לו [רבי] מפני מה אתה מיצר אמר לו (רבי) עקיבא ראוי לו שיפול למטה י"ב חדש ואל יגזור עליו גזירה זו א"ל רבי תרשיני לומר לפניך דבר אחד שלמדתני אמר לו אמור אמר לו הרי הוא אומר (ויקרא כג, ב) אתם אתם אתם ג' פעמים אתם אפילו שוגגין אתם אפילו מזידין אתם אפילו מוטעין בלשון הזה אמר לו עקיבא נחמתני נחמתני:
§ The mishna taught that Rabbi Akiva went and found him distressed that the head of the Great Sanhedrin was forcing him to desecrate the day that he maintained was Yom Kippur. A dilemma was raised before the Sages: Who was distressed? Was Rabbi Akiva distressed or was Rabbi Yehoshua distressed? The Gemara answers: Come and hear, as it is taught in a baraita: Rabbi Akiva went and found Rabbi Yehoshua in a state of distress, and he said to him: My teacher, for what reason are you distressed? Rabbi Yehoshua said to him: Rabbi Akiva, it is fitting for one to fall sick in bed for twelve months, rather than to have this decree issued against him that he should have to desecrate Yom Kippur. Rabbi Akiva said to him: My teacher, allow me to say before you one matter that you yourself once taught me. He said to him: Speak. He said to him: It states with respect to the Festivals: “The appointed seasons of the Lord, which you shall proclaim them [otam] to be sacred convocations (Leviticus 23:2). And it is written: “These are the appointed seasons of the Lord, sacred convocations; you shall proclaim them [otam] in their season” (Leviticus 23:4). And it is written: “These are the appointed seasons of the Lord; you shall proclaim them [otam] to be sacred convocations” (Leviticus 23:37). Three times the verses use the term: Them [otam], which can also be read as you [atem], in plural. This comes to teach: You [atem] are authorized to determine the date of the new month, even if you unwittingly establish the New Moon on the wrong day; you, even if you do so intentionally; you, even if you are misled by false witnesses. In all cases, once the court establishes the day as the New Moon, it is sanctified, and God grants His consent. After hearing this, Rabbi Yehoshua said to him in these words: Akiva, you have consoled me; you have consoled me.
נטל מקלו ומעותיו בידו: תנו רבנן כיון שראה אותו עמד מכסאו ונשקו על ראשו אמר לו שלום עליך רבי ותלמידי רבי שלמדתני תורה ברבים ותלמידי שאני גוזר עליך גזירה ואתה מקיימה כתלמיד אשרי הדור שהגדולים נשמעים לקטנים קל וחומר קטנים לגדולים קל וחומר חיובא הוא אלא מתוך שהגדולים נשמעים לקטנים נושאין קטנים קל וחומר בעצמן:
§ The mishna taught: Rabbi Yehoshua took his staff and his money in his hand, and appeared before Rabban Gamliel on the day on which Yom Kippur occurred according to his calculation, as Rabban Gamliel had ordered him to do. The Sages taught in a baraita: When Rabban Gamliel saw Rabbi Yehoshua, he rose from his chair and kissed him on his head and said to him: Peace be on you, my teacher and my student. My teacher, as you have taught me Torah in public, and my student, as I issue a decree against you and you fulfill it like a student of mine. Fortunate is the generation in which the greater heed the lesser, and it is an a fortiori inference that the generation in which the lesser heed the greater is certainly fortunate as well. The Gemara questions this last point: Is this derived by an a fortiori inference? This is incorrect, as it is an obligation for the lesser to heed those who are greater than them. Rather, Rabbi Gamliel meant the following: Since the greater heed the lesser, the lesser apply an a fortiori inference to themselves and heed the leaders of the generation.
אֲמַר לֵיהּ רָבָא בַּר רַב חָנָן לְאַבָּיֵי: הִילְכְתָא מַאי? אֲמַר לֵיהּ: פּוֹק חֲזִי מַאי עַמָּא דָבַר. אִיכָּא דְּמַתְנֵי לַהּ אַהָא: הַשּׁוֹתֶה מַיִם לִצְמָאוֹ, אוֹמֵר: ״שֶׁהַכֹּל נִהְיָה בִּדְבָרוֹ״. רַבִּי טַרְפוֹן אוֹמֵר: ״בּוֹרֵא נְפָשׁוֹת רַבּוֹת וְחֶסְרוֹנָן עַל כָּל מַה שֶּׁבָּרָאתָ״. אֲמַר לֵיהּ רַב חָנָן לְאַבָּיֵי: הִלְכְתָא מַאי? אֲמַר לֵיהּ: פּוֹק חֲזִי מַאי עַמָּא דָבַר.
Rava bar Rav Ḥanan said to Abaye: What is the accepted halakha with regard to the width of a side post? He said to him: Go out and observe what the people are doing; it is common practice to rely on a side post of minimal width. The Gemara notes that there are those who taught that this answer was given with regard to this discussion: One who drinks water to quench his thirst recites the following blessing prior to drinking: By Whose word all things came to be. Rabbi Tarfon disagrees and says he recites the blessing: Who creates the many forms of life and their needs, for all that You have created. Rav Ḥanan said to Abaye: What is the halakha? He said to him: Go out and observe what the people are doing; the customary practice is to say: By Whose word all things came to be.
