Segment 1א׳

וְאִית הַשְׁבָּתַת מְלָאכָה, כְּגוֹן שׁוֹר, דְּאִית לֵיהּ עוֹל. וַחֲמוֹר, דְּאִית לֵיהּ מַשְׂאוֹי. בֵּין עוֹל מַלְכוּת שָׁמַיִם, כְּגוֹן תְּפִילִין. בֵּין עוֹל מַלְכוּת עֲבוֹדַת כּוֹכָבִים וּמַזָּלוֹת, כְּפוּם עוֹבָדַיְיהוּ, בְּאִלֵּין יוֹמִין אִית לוֹן הַשְׁבָּתַת מְלָאכָה וְנַיְיחָא. מַאן דְּלָא אִתְעֲסַּק בְּאוֹרַיְיתָא וּבְפִקּוּדִין, אִית לֵיהּ עוֹל מַלְכוּת עֲבוֹדַת כּוֹכָבִים וּמַזָּלוֹת. וּמַאן דְּאִתְעֲסָּק בְּאוֹרַיְיתָא וּבְפִקּוּדִין, אִית לוֹן עוֹל מַלְכוּת שָׁמַיִם, דְּאִיהִי ה' בַּתְרָאָה, מַלְכוּת שָׁמַיִם אִתְקְרִיאַת.

And there is a ceasing from labour, as in the ox, which has a yoke, and the ass, which has a burden — whether the yoke of the kingdom of Heaven, as in phylacteries, or the yoke of the kingdom of idolatry, each according to their deeds. On these days they have a ceasing from labour and rest. One who does not occupy himself with Torah and with commandments has the yoke of the kingdom of idolatry; and one who does occupy himself with Torah and with commandments, they have the yoke of the kingdom of Heaven, which is the last He, and is called the kingdom of Heaven.

Segment 2ב׳

עוֹל מִצְּוֹת אִיהִי וַדַּאי, בְּגִין דְּבָהּ אִתְבְּרִיאוּ כָּל בִּרְיָין דִּשְׁמַיָּא וְאַרְעָא, הֲדָא הוּא דִכְתִיב, (בראשית ב׳:ד׳) אֵלֶּה תוֹלְדוֹת הַשָּׁמַיִם וְהָאָרֶץ בְּהִבָּרְאָם. בְּה' בְּרָאָם. וְכַד יֵיתֵי שַׁבָּת וְיוֹם טוֹב, נַחְתַּת בִּינָה דְּאִיהוּ יד"ו, עַל ה', דְּאִיהִי מַלְכוּת שָׁמַיִם נְשָׁמָה יְתֵירָה, וְאִיהוּ (שמות ל״ב:ט״ז) חָרוּת עַל הַלּוּחוֹת. אָנֹכִי בִּיצִּיאַת מִצְּרַיִם, וּפְרִישַׁת גַּדְפָהָא עַל בְּרַתָּא, וְעַל מַשִּׁרְיָין דִּילָהּ, וְאִית לוֹן נַיְיחָא. וְאִתְּמַר בְּמַשִּׁרְיָין דְּסָמָאֵ"ל וְנָחָשׁ, (דברים כ״ח:י׳) וְרָאוּ כָּל עַמֵּי הָאָרֶץ כִּי שֵׁם יְיָ' נִקְרָא עָלֶיךָ וְיָרְאוּ מִמֶּךָ, אוֹת תְּפִלִין וְאוֹת שַׁבָּת, וְאוֹת דְּיוֹמִין טָבִין, וְאוֹת בְּרִית כֻּלְּהוּ שְׁקִילִין.

This is the yoke of the commandments, obviously, in the sense that in it all that was created in the heaven and earth - one [reason for this] is what is written "these are the generations of heaven and earth as they were created" (Gen. 2:4) BEHIBARAM - they were created with HEY. And so there are Shabbat and the Holy Days, [when] Binah comes down, which is His hand on Hey, which is the Reign of Heaven [God's] which is the Extra Soul, meaning "carved on the tablets" (Exodus 32:16), the I of the exodus from Egypt (see Exodus 20:2) and the extending of the wings over the daughter, and over those who serve her, and they have rest. And this verse is said regarding the servants of Samae"l and the snake: " And all the peoples of the earth shall see that the Ad-nai’s name is proclaimed over you and they shall stand in fear of you. " (Deut. 28:10) - this is the mark of tefillin and the mark of Shabbat, and the mark of the Holy Days and the mark of the Brit - all [4 marks] are similar [in this].

Segment 3ג׳

וְאִית אוֹת דְּשַׁדַּ"י, דְּאִיהוּ מְטַטְרוֹ"ן עֶבֶד, וְכַמָּה עַבָדִין תַּלְיָין מִנֵּיהּ, דִּמְמָנָא עַל אִלֵּין דְּעַבְדִין פִּקּוּדֵי עַל מְנָת לְקַבֵּל פְּרָס. מְטַטְרוֹ"ן וּמַשִּׁרְיָין דִּילֵיהּ מְמָנָן עָלַיְיהוּ. בְּגִינַיְיהוּ אִתְּמַר, (שמות כ״ג:י״ב) לְמַעַן יָנוּחַ שׁוֹרְךָ וַחֲמוֹרֶךָ וְעַבְדְךָ וַאֲמָתְךָ. אֲבָל אִינּוּן דְּעַבְדִין פִּקוּדִין שֶׁלֹּא עַל מְנָת לְקַבֵּל פְּרָס, אִינּוּן בְּנוֹי דְּמַלְכָּא וּמַטְרוֹנִיתָא. וְאִינּוּן כִּתְרִין וְתָגִין עַל רֵישָׁא, דְּעַבָדִין בְּיוֹמִין דְּחוֹל. וּבְגִינַיְיהוּ אִתְּמַר וּדְאִשְׁתַּמַּשׁ בְּתָגָא חֲלָף, וְהַזָּר הַקָּרֵב לְגַבַּיְיהוּ יוּמַת. דְּשַׁבָּתּוֹת אִתְקְרִיאוּ לְגַבֵּי עַבָדִין.

And there is the mark of Shad"ai, that is Metatro"n as servant, and many servants are dependent on him, that he is the appointed one on those who are servants in order to receive a reward (see Avot 1:3). Metatro"n and his servants are appointed over them. And regarding them it is said: "so that your ox and your donkey and your slave and your female slave rest" (Exodus 23:12). But those who observe/follow/serve the commandments without the intention of receiving a reward, those are the children of the King and the Matronita. And they are the crowns and the adornments on the head, that serve on the common days. And regarding them it is said "and those who make use of the crown disappear" (Avot 1:13) and "the stranger that comes" on them "will die" since the Shabatot are called for the servants.
