But afterward after the Torah was given their sin caused both them and the world to become gross [again]—until the End of days when G-d’s “right hand” (ימין meaning both “days” and “right”), i.e., His power, will be revealed.

רַק שֶׁאַחַר כָּךְ גָּרַם הַחֵטְא וְנִתְגַּשְּׁמוּ הֵם וְהָעוֹלָם, עַד עֵת קֵץ הַיָּמִין,

Then, the dross of the body and of the world will be refined, and they will be able to receive the revelation of G-d’s light that will shine forth over Israel by means of the Torah, which is called “might.”

שֶׁאָז יִזְדַּכֵּךְ גַּשְׁמִיּוּת הַגּוּף וְהָעוֹלָם, וְיוּכְלוּ לְקַבֵּל גִּילּוּי אוֹר ה', שֶׁיָּאִיר לְיִשְׂרָאֵל עַל יְדֵי הַתּוֹרָה שֶׁנִּקְרֵאת "עוֹז".

Through the superabundance of light which will shine upon the Jewish people, the darkness of the nations will also be lit up,

וּמִיִּתְרוֹן הַהֶאָרָה לְיִשְׂרָאֵל – יַגִּיהַּ חשֶׁךְ הָאוּמּוֹת גַּם כֵּן,

as it is written: “And nations will walk by your (the Jewish people’s) light,”17

כְּדִכְתִיב: "וְהָלְכוּ גוֹיִם לְאוֹרֵךְ וְגוֹ'",

and it is also written that the nations will say to the Jewish people: “House of Jacob, go, and we will walk along by the light of G-d,”18

וּכְתִיב: "בֵּית יַעֲקֹב לְכוּ וְנֵלְכָה בְּאוֹר ה'",

and again: “And the glory of G-d shall be revealed, and all flesh will see,”…19

וּכְתִיב: "וְנִגְלָה כְּבוֹד ה', וְרָאוּ כָל בָּשָׂר יַחְדָּיו וְגוֹ'",

and: “To enter the holes of the rocks and the clefts of the boulders for fear of G-d and of His majestic glory.”20

וּכְתִיב: "לָבוֹא בְּנִקְרֹת הַצּוּרִים וּבִסְעִיפֵי הַסְּלָעִים מִפְּנֵי פַּחַד ה' וַהֲדַר גְּאוֹנוֹ וְגוֹ'",

This refers to the nations, who will be filled with the dread of G-d, for it cannot be said of Israel, who will be one with G-d, that they will seek refuge from Him.

So also do we pray: “Appear in the majestic splendor of Your might over all the inhabitants of the world,”21 including the other nations.

וּכְמוֹ שֶׁאוֹמְרִים: "וְהוֹפַע בַּהֲדַר גְּאוֹן עוּזֶּךָ עַל כָּל יוֹשְׁבֵי תֵבֵל אַרְצֶךָ וְגוֹ'":

Thus, we see that in the Messianic era, G-dliness will be revealed to all the nations of the world—and in this state lies the fulfillment of the purpose for which this world was created.
