Moshe tells the Jews that the Torah is the focal point of life and living, around which all other things revolve:
ה אֱלֹהֵינוּ דִּבֶּר אֵלֵינוּ, בְּחֹרֵב לֵאמֹר: רַב-לָכֶם שֶׁבֶת, בָּהָר הַזֶּה. פְּנוּ וּסְעוּ לָכֶם, וּבֹאוּ הַר הָאֱמֹרִי וְאֶל-כָּל-שְׁכֵנָיו, בָּעֲרָבָה בָהָר וּבַשְּׁפֵלָה וּבַנֶּגֶב, וּבְחוֹף הַיָּם–אֶרֶץ הַכְּנַעֲנִי וְהַלְּבָנוֹן, עַד-הַנָּהָר הַגָּדֹל נְהַר-פְּרָת – “Our God spoke to us at Sinai, saying, “You have dwelt long enough at this mountain. Travel to the mountain of Emori, and to all its neighbouring places, in the plain, on the mountain, and in the lowland, and in the south and by the seashore, the land of the Canaanites, and the Lebanon, until the great river…”” (1:6,7)
Sinai was a monumental event. Rashi notes how at that moment, the Jews were given Torah, mitzvos, the Mishkan, its utensils, government.
R Ahron Bakst notes that the opening mention of Sinai does not continue with further discussion of that incredible moment, but rather, that the Jews must move on. Moshe says that once Sinai is achieved and actualised, פְּנוּ וּסְעוּ לָכֶם – it’s time to get going.
The Torah is תורת חיים – instructions for living. R Shamshon Raphael Hirsch notes that the Torah is given in the desert – a bubble, a vacuum of civilisation. Their economy was suspended for forty years – everything was free, easy, and abundant. Life was elemental. Life was stripped of its grandeur, power and glory; they were in the womb, so to speak. This is how the Torah is earned and acquired.
This is also the function of exile – a return to the wilderness, a return to the womb to reacquaint ourselves with our duties.
Moshe told the people that if the heights of the Torah can be retained, going out into the world is not scary; it is natural. This is the shining light we can be.
