What is so significant about today in Jewish history?
וַיְהִי֙ בְּאַרְבָּעִ֣ים שָׁנָ֔ה בְּעַשְׁתֵּֽי־עָשָׂ֥ר חֹ֖דֶשׁ בְּאֶחָ֣ד לַחֹ֑דֶשׁ דִּבֶּ֤ר מֹשֶׁה֙ אֶל־בְּנֵ֣י יִשְׂרָאֵ֔ל כְּ֠כֹל אֲשֶׁ֨ר צִוָּ֧ה יְהוָ֛ה אֹת֖וֹ אֲלֵהֶֽם׃
It was in the fortieth year, on the first day of the eleventh month, that Moses addressed the Israelites in accordance with the instructions that the LORD had given him for them,
אַחֲרֵ֣י הַכֹּת֗וֹ אֵ֚ת סִיחֹן֙ מֶ֣לֶךְ הָֽאֱמֹרִ֔י אֲשֶׁ֥ר יוֹשֵׁ֖ב בְּחֶשְׁבּ֑וֹן וְאֵ֗ת ע֚וֹג מֶ֣לֶךְ הַבָּשָׁ֔ן אֲשֶׁר־יוֹשֵׁ֥ב בְּעַשְׁתָּרֹ֖ת בְּאֶדְרֶֽעִי׃
after he had defeated Sihon king of the Amorites, who dwelt in Heshbon, and King Og of Bashan, who dwelt at Ashtaroth [and] Edrei.
בְּעֵ֥בֶר הַיַּרְדֵּ֖ן בְּאֶ֣רֶץ מוֹאָ֑ב הוֹאִ֣יל מֹשֶׁ֔ה בֵּאֵ֛ר אֶת־הַתּוֹרָ֥ה הַזֹּ֖את לֵאמֹֽר׃
On the other side of the Jordan, in the land of Moab, Moses undertook to expound this Teaching. He said:
באר את התורה. בְּשִׁבְעִים לָשׁוֹן פֵּרְשָׁהּ לָהֶם (תנחומא; ע' סוטה ל"ב):
באר את התורה [MOSES BEGAN] TO EXPLAIN THIS LAW — in the seventy languages of the ancient world did he explain it to them (Midrash Tanchuma, Devarim 2; Genesis Rabbah 49; cf. Sotah 32a and Rashi on Deuteronomy 27:8).
Making it everlasting & meeting the needs of all learners
וַיְצַ֤ו מֹשֶׁה֙ וְזִקְנֵ֣י יִשְׂרָאֵ֔ל אֶת־הָעָ֖ם לֵאמֹ֑ר שָׁמֹר֙ אֶת־כָּל־הַמִּצְוָ֔ה אֲשֶׁ֧ר אָנֹכִ֛י מְצַוֶּ֥ה אֶתְכֶ֖ם הַיּֽוֹם׃
Moses and the elders of Israel charged the people, saying: Observe all the Instruction that I enjoin upon you this day.
וְהָיָ֗ה בַּיּוֹם֮ אֲשֶׁ֣ר תַּעַבְר֣וּ אֶת־הַיַּרְדֵּן֒ אֶל־הָאָ֕רֶץ אֲשֶׁר־יְהוָ֥ה אֱלֹהֶ֖יךָ נֹתֵ֣ן לָ֑ךְ וַהֲקֵמֹתָ֤ לְךָ֙ אֲבָנִ֣ים גְּדֹל֔וֹת וְשַׂדְתָּ֥ אֹתָ֖ם בַּשִּֽׂיד׃
As soon as you have crossed the Jordan into the land that the LORD your God is giving you, you shall set up large stones. Coat them with plaster
וְכָתַבְתָּ֣ עֲלֵיהֶ֗ן אֶֽת־כָּל־דִּבְרֵ֛י הַתּוֹרָ֥ה הַזֹּ֖את בְּעָבְרֶ֑ךָ לְמַ֡עַן אֲשֶׁר֩ תָּבֹ֨א אֶל־הָאָ֜רֶץ אֲֽשֶׁר־יְהוָ֥ה אֱלֹהֶ֣יךָ ׀ נֹתֵ֣ן לְךָ֗ אֶ֣רֶץ זָבַ֤ת חָלָב֙ וּדְבַ֔שׁ כַּאֲשֶׁ֥ר דִּבֶּ֛ר יְהוָ֥ה אֱלֹהֵֽי־אֲבֹתֶ֖יךָ לָֽךְ׃
and inscribe upon them all the words of this Teaching. When you cross over to enter the land that the LORD your God is giving you, a land flowing with milk and honey, as the LORD, the God of your fathers, promised you—
וְכָתַבְתָּ֣ עַל־הָאֲבָנִ֗ים אֶֽת־כָּל־דִּבְרֵ֛י הַתּוֹרָ֥ה הַזֹּ֖את בַּאֵ֥ר הֵיטֵֽב׃ (ס)
And on those stones you shall inscribe every word of this Teaching most distinctly.
באר היטב. בְּשִׁבְעִים לָשׁוֹן (שם ל"ב):
באר היטב EXPLAINING THEM WELL — i.e. in seventy languages (Sotah 32a; cf. Rashi on Deuteronomy 1:5).
Internalizing Torah
אֶֽת־הַדְּבָרִ֣ים הָאֵ֡לֶּה דִּבֶּר֩ יְהוָ֨ה אֶל־כָּל־קְהַלְכֶ֜ם בָּהָ֗ר מִתּ֤וֹךְ הָאֵשׁ֙ הֶֽעָנָ֣ן וְהָֽעֲרָפֶ֔ל ק֥וֹל גָּד֖וֹל וְלֹ֣א יָסָ֑ף וַֽיִּכְתְּבֵ֗ם עַל־שְׁנֵי֙ לֻחֹ֣ת אֲבָנִ֔ים וַֽיִּתְּנֵ֖ם אֵלָֽי׃
The LORD spoke those words—those and no more—to your whole congregation at the mountain, with a mighty voice out of the fire and the dense clouds. He inscribed them on two tablets of stone, which He gave to me.
How do we tap into our own Divine inspiration? How do we add to Torah?
