בראשית. אָמַר רַבִּי יִצְחָק לֹֹֹֹֹא הָיָה צָרִיךְ לְהַתְחִיל אֶת הַתּוֹרָה אֶלָּא מֵ"הַחֹדֶשׁ הַזֶּה לָכֶם", שֶׁהִיא מִצְוָה רִאשׁוֹנָה שֶׁנִּצְטַוּוּ בָּהּ יִשׂרָאֵל, וּמַה טַּעַם פָּתַח בִּבְרֵאשִׁית?
בראשית IN THE BEGINNING — Rabbi Isaac said: The Torah which is the Law book of Israel should have commenced with the verse (Exodus 12:2) “This month shall be unto you the first of the months” which is the first commandment given to Israel. What is the reason, then, that it commences with the account of the Creation?
- What exactly is this mitzvah?
- Why do you think our first mitzvah as a nation is this one?

... אָמַר לוֹ רַבִּי יְהוֹשֻׁעַ: רוֹאֶה אֲנִי אֶת דְּבָרֶיךָ. שָׁלַח לוֹ רַבָּן גַּמְלִיאֵל: גּוֹזְרַנִי עָלֶיךָ שֶׁתָּבֹא אֶצְלִי בְּמַקֶּלְךָ וּבִמְעוֹתֶיךָ בְּיוֹם הַכִּפּוּרִים שֶׁחָל לִהְיוֹת בְּחֶשְׁבּוֹנֶךָ. הָלַךְ וּמְצָאוֹ רַבִּי עֲקִיבָא מֵיצֵר, אָמַר לוֹ: יֵשׁ לִי לִלְמוֹד שֶׁכׇּל מַה שֶּׁעָשָׂה רַבָּן גַּמְלִיאֵל עָשׂוּי, שֶׁנֶּאֱמַר: ״אֵלֶּה מוֹעֲדֵי ה׳ מִקְרָאֵי קֹדֶשׁ אֲשֶׁר תִּקְרְאוּ אֹתָם״, בֵּין בִּזְמַנָּן בֵּין שֶׁלֹּא בִּזְמַנָּן — אֵין לִי מוֹעֲדוֹת אֶלָּא אֵלּוּ. בָּא לוֹ אֵצֶל רַבִּי דּוֹסָא בֶּן הוֹרְכִּינָס, אָמַר לוֹ: אִם בָּאִין אָנוּ לָדוּן אַחַר בֵּית דִּינוֹ שֶׁל רַבָּן גַּמְלִיאֵל, צְרִיכִין אָנוּ לָדוּן אַחַר כׇּל בֵּית דִּין וּבֵית דִּין שֶׁעָמַד מִימוֹת מֹשֶׁה וְעַד עַכְשָׁיו. שֶׁנֶּאֱמַר: ״וַיַּעַל מֹשֶׁה וְאַהֲרֹן נָדָב וַאֲבִיהוּא וְשִׁבְעִים מִזִּקְנֵי יִשְׂרָאֵל״, וְלָמָּה לֹא נִתְפָּרְשׁוּ שְׁמוֹתָן שֶׁל זְקֵנִים? אֶלָּא לְלַמֵּד שֶׁכׇּל שְׁלֹשָׁה וּשְׁלֹשָׁה שֶׁעָמְדוּ בֵּית דִּין עַל יִשְׂרָאֵל — הֲרֵי הוּא כְּבֵית דִּינוֹ שֶׁל מֹשֶׁה. נָטַל מַקְלוֹ וּמְעוֹתָיו בְּיָדוֹ, וְהָלַךְ לְיַבְנֶה אֵצֶל רַבָּן גַּמְלִיאֵל בַּיּוֹם שֶׁחָל יוֹם הַכִּפּוּרִים לִהְיוֹת בְּחֶשְׁבּוֹנוֹ. עָמַד רַבָּן גַּמְלִיאֵל וּנְשָׁקוֹ עַל רֹאשׁוֹ, אָמַר לוֹ: בּוֹא בְּשָׁלוֹם רַבִּי וְתַלְמִידִי! רַבִּי — בְּחׇכְמָה, וְתַלְמִידִי — שֶׁקִּבַּלְתָּ אֶת דְּבָרַי.
...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.
- What factors do you think are driving the desire to go for Rabban Gamliel's start of the month?
- Why does Rabbi Yehoshua ultimately go with Rabban Gamliel even though he thinks Rabban Gamliel is wrong?
- What do you think of Rabban Gamliel's behaviour?
THE TAKEAWAY: HUMAN PARTNERSHIP IN DIVINE LAW
Rav Aharon Lichtenstein, Seeking His Presence: Conversations with Rabbi Aharon Lichtenstein, pgs. 147-148
"...But if even if there are other witnesses, and even if we are already talking about the thirty-first day, when we know even without witnesses when the new month will be celebrated, (because a month cannot last thirty-two days) why are the witnesses allowed to desecrate the Sabbath in order to go up to Jerusalem?
The Mishna in Rosh haShana (2:7) teaches that 'whether the moon was seen at its proper time or not, they sanctify it.' This means that even if thirty days have gone by, and there is no need for witnesses to help determine the start of the new month, nonetheless the court sanctifies it. There is a qualitative difference between a month sanctified automatically and one sanctified by the court based on the testimony of witnesses, and this discrepancy even justifies desecrating the Sabbath...
We see from here that even in a case where the start of the month is already obvious, and thus the witnesses will have no impact on setting the calendar at all, the witnesses make a qualitative difference in the nature of the sanctification of the new moon. The question is always whether the new month be established with sanctification by man or not. If witnesses come forth, then the new month will be sanctified by man, and this warrants desecrating the Sabbath."
- Why does Rav Lichtenstein say that sanctifying the moon is important enough to desecrate Shabbat?
- With this understanding, why do you think then sanctifying the moon is the first mitzvah for the Jewish people?
