(2) This month shall mark for you the beginning of the months; it shall be the first of the months of the year for you.
(א) בראשית. אָמַר רַבִּי יִצְחָק לֹֹֹֹֹא הָיָה צָרִיךְ לְהַתְחִיל אֶת הַתּוֹרָה אֶלָּא מֵהַחֹדֶשׁ הַזֶּה לָכֶם, שֶׁהִיא מִצְוָה רִאשׁוֹנָה שֶׁנִּצְטַוּוּ בָּהּ יִשׂרָאֵל, וּמַה טַּעַם פָּתַח בִּבְרֵאשִׁית? מִשׁוּם כֹּחַ מַעֲשָׂיו הִגִּיד לְעַמּוֹ לָתֵת לָהֶם נַחֲלַת גּוֹיִם (תהילים קי"א), שֶׁאִם יֹאמְרוּ אֻמּוֹת הָעוֹלָם לְיִשְׁרָאֵל לִסְטִים אַתֶּם, שֶׁכְּבַשְׁתֶּם אַרְצוֹת שִׁבְעָה גוֹיִם, הֵם אוֹמְרִים לָהֶם כָּל הָאָרֶץ שֶׁל הַקָּבָּ"ה הִיא, הוּא בְרָאָהּ וּנְתָנָהּ לַאֲשֶׁר יָשַׁר בְּעֵינָיו, בִּרְצוֹנוֹ נְתָנָהּ לָהֶם, וּבִרְצוֹנוֹ נְטָלָהּ מֵהֶם וּנְתָנָהּ לָנוּ:
(1) 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? Because of the thought expressed in the text (Psalms 111:6) “He declared to His people the strength of His works (i.e. He gave an account of the work of Creation), in order that He might give them the heritage of the nations.” For should the peoples of the world say to Israel, “You are robbers, because you took by force the lands of the seven nations of Canaan”, Israel may reply to them, “All the earth belongs to the Holy One, blessed be He; He created it and gave it to whom He pleased. When He willed He gave it to them, and when He willed He took it from them and gave it to us” (Yalkut Shimoni on Torah 187).
תַּנְיָא רַבִּי אֱלִיעֶזֶר אוֹמֵר בְּתִשְׁרִי נִבְרָא הָעוֹלָם בְּתִשְׁרִי נוֹלְדוּ אָבוֹת בְּתִשְׁרִי מֵתוּ אָבוֹת בַּפֶּסַח נוֹלַד יִצְחָק בְּרֹאשׁ הַשָּׁנָה נִפְקְדָה שָׂרָה רָחֵל וְחַנָּה בְּרֹאשׁ הַשָּׁנָה יָצָא יוֹסֵף מִבֵּית הָאֲסוּרִין
It is taught in a baraita that the tanna’im disagreed about this point: Rabbi Eliezer says: In Tishrei the world was created; in Tishrei the Patriarchs were born; in Tishrei the Patriarchs died; on Passover Isaac was born; on Rosh HaShana Sarah, Rachel, and Hannah were remembered by God and conceived; on Rosh HaShana Joseph came out from prison;
בְּרֹאשׁ הַשָּׁנָה בָּטְלָה עֲבוֹדָה מֵאֲבוֹתֵינוּ בְּמִצְרַיִם בְּנִיסָן נִגְאֲלוּ בְּתִשְׁרִי עֲתִידִין לִיגָּאֵל רַבִּי יְהוֹשֻׁעַ אוֹמֵר בְּנִיסָן נִבְרָא הָעוֹלָם בְּנִיסָן נוֹלְדוּ אָבוֹת בְּנִיסָן מֵתוּ אָבוֹת בְּפֶסַח נוֹלַד יִצְחָק בְּרֹאשׁ הַשָּׁנָה נִפְקְדָה שָׂרָה רָחֵל וְחַנָּה בְּרֹאשׁ הַשָּׁנָה יָצָא יוֹסֵף מִבֵּית הָאֲסוּרִין בְּרֹאשׁ הַשָּׁנָה בָּטְלָה עֲבוֹדָה מֵאֲבוֹתֵינוּ בְּמִצְרַיִם בְּנִיסָן נִגְאֲלוּ בְּנִיסָן עֲתִידִין לִיגָּאֵל

on Rosh HaShana our forefathers’ slavery in Egypt ceased; in Nisan the Jewish people were redeemed from Egypt; and in Tishrei in the future the Jewish people will be redeemed in the final redemption with the coming of the Messiah. Rabbi Yehoshua disagrees and says: In Nisan the world was created; in Nisan the Patriarchs were born; in Nisan the Patriarchs died; on Passover Isaac was born; on Rosh HaShana Sarah, Rachel, and Hannah were remembered by God and conceived sons; on Rosh HaShana Joseph came out from prison; on Rosh HaShana our forefathers’ slavery in Egypt ceased; in Nisan the Jewish people were redeemed from Egypt; and in Nisan in the future the Jewish people will be redeemed in the final redemption.
