In the beginning...
בְּרֵאשִׁ֖ית בָּרָ֣א אֱלֹהִ֑ים אֵ֥ת הַשָּׁמַ֖יִם וְאֵ֥ת הָאָֽרֶץ׃
When God began to create heaven and earth—
Beginning of a shared, measured time
הַחֹ֧דֶשׁ הַזֶּ֛ה לָכֶ֖ם רֹ֣אשׁ חֳדָשִׁ֑ים רִאשׁ֥וֹן הוּא֙ לָכֶ֔ם לְחׇדְשֵׁ֖י הַשָּׁנָֽה׃
This month shall be to you the beginning of months: it shall be the first month of the year to you.
עַל שִׁשָּׁה חֳדָשִׁים הַשְּׁלוּחִין יוֹצְאִין, עַל נִיסָן מִפְּנֵי הַפֶּסַח, עַל אָב מִפְּנֵי הַתַּעֲנִית, עַל אֱלוּל מִפְּנֵי רֹאשׁ הַשָּׁנָה, עַל תִּשְׁרֵי מִפְּנֵי תַקָּנַת הַמּוֹעֲדוֹת, עַל כִּסְלֵו מִפְּנֵי חֲנֻכָּה, וְעַל אֲדָר מִפְּנֵי הַפּוּרִים. וּכְשֶׁהָיָה בֵית הַמִּקְדָּשׁ קַיָּם, יוֹצְאִין אַף עַל אִיָּר מִפְּנֵי פֶסַח קָטָן:
In six months of the year the messengers go out from the court in Jerusalem to report throughout Eretz Yisrael and the Diaspora which day was established as the New Moon, the thirtieth or the thirty-first day since the previous New Moon. They go out in the month of Nisan, due to Passover, so that people will know on which day to celebrate it; in the month of Av, due to the fast of the Ninth of Av; in Elul, due to Rosh HaShana, which begins thirty days after the New Moon of Elul; in Tishrei, due to the need to establish the correct dates on which to celebrate the Festivals of Tishrei, i.e., Yom Kippur and Sukkot; in Kislev, due to Hanukkah; and in Adar, due to Purim. And when the Temple was standing, messengers would also go out in the month of Iyyar due to small Passover, i.e., second Pesaḥ, which occurs on the fourteenth of Iyyar. This holiday allowed those who were ritually impure or on a distant journey on the fourteenth of Nisan, and therefore incapable of bringing the Paschal lamb at that time, to bring their Paschal lamb a month later.
בֵּין שֶׁנִּרְאָה בַעֲלִיל בֵּין שֶׁלֹּא נִרְאָה בַעֲלִיל, מְחַלְּלִין עָלָיו אֶת הַשַּׁבָּת, רַבִּי יוֹסֵי אוֹמֵר, אִם נִרְאָה בַעֲלִיל, אֵין מְחַלְּלִין עָלָיו אֶת הַשַּׁבָּת:
Whether the new moon was seen clearly [ba’alil] by everyone or whether it was not clearly seen, one may desecrate Shabbat in order to testify before the court. Rabbi Yosei says: If the moon was clearly seen, they may not desecrate Shabbat for it, since other witnesses, located nearer to the court, will certainly testify. If these distant witnesses go to court to testify, they will desecrate Shabbat unnecessarily.
Beginning of a symbolic time
מִתְּחִלָּה עוֹבְדֵי עֲבוֹדָה זָרָה הָיוּ אֲבוֹתֵינוּ, וְעַכְשָׁיו קֵרְבָנוּ הַמָּקוֹם לַעֲבדָתוֹ, שֶׁנֶּאֱמַר: וַיֹאמֶר יְהוֹשֻעַ אֶל־כָּל־הָעָם, כֹּה אָמַר ה' אֱלֹהֵי יִשְׂרָאֵל: בְּעֵבֶר הַנָּהָר יָשְׁבוּ אֲבוֹתֵיכֶם מֵעוֹלָם, תֶּרַח אֲבִי אַבְרָהָם וַאֲבִי נָחוֹר, וַיַּעַבְדוּ אֱלֹהִים אֲחֵרִים.
From the beginning, our ancestors were idol worshipers. And now, the Place [of all] has brought us close to His worship, as it is stated (Joshua 24:2-4), "Yehoshua said to the whole people, so said the Lord, God of Israel, 'Over the river did your ancestors dwell from always, Terach the father of Avraham and the father of Nachor, and they worshiped other gods.
At the end...
בַּצַּ֣ר לְךָ֔ וּמְצָא֕וּךָ כֹּ֖ל הַדְּבָרִ֣ים הָאֵ֑לֶּה בְּאַחֲרִית֙ הַיָּמִ֔ים וְשַׁבְתָּ֙ עַד־יְהֹוָ֣ה אֱלֹהֶ֔יךָ וְשָׁמַעְתָּ֖ בְּקֹלֽוֹ׃
When you are in distress and all these things happen to you, at the end of time, you will return to Adonoy, your God, and will obey Him.
הוו יודעין שלא כדיני ממונות דיני נפשות דיני ממונות אדם נותן ממון ומתכפר לו דיני נפשות דמו ודם זרעותיו תלויין בו עד סוף העולם
Know that capital cases are not like monetary cases. [With regard to] monetary cases, [a false witness] gives money and it absolves him. [With regard to] capital cases, the blood [of the victim] and the blood of his [unborn] descendants is hung on [the false witness] until the end of time, for so we find about Cain, who killed his brother, as it is said, "Your brother's bloods (demei) are crying out (Genesis 4:10)--" it does not say 'Your brothers blood (dam)', but rather 'Your brother's bloods (demei)'-- his blood and the blood of his [unborn] descendants.
אִֽם־יִשְׁמְר֬וּ בָנֶ֨יךָ ׀ בְּרִיתִי֮ וְעֵדֹתִ֥י ז֗וֹ אֲלַ֫מְּדֵ֥ם גַּם־בְּנֵיהֶ֥ם עֲדֵי־עַ֑ד יֵ֝שְׁב֗וּ לְכִסֵּא־לָֽךְ׃
If your sons keep My covenant
and My decrees that I teach them,
then their sons also,
to the end of time,
shall sit upon your throne.”
and My decrees that I teach them,
then their sons also,
to the end of time,
shall sit upon your throne.”
