Segment 1א׳

תָּא חֲזֵי, לֵאָה אוֹלִידַת שִׁית בְּנִין וּבְרַתָּא חָדָא. וְהָכִי אִתְחֲזֵי, דְּהָא שִׁית סִטְרִין קָיְימִין עֲלָהּ וְאִלֵּין שִׁית, וּבְרַתָּא חָדָא, בְּרָזָא עִלָּאָה נָפְקָא.

Observe that Leah bore six sons and one daughter. That was in the order of things, since six world-directions were stationed above her, and so the six sons and one daughter formed a symbol of the grades.

Segment 2ב׳

רָחֵל אוֹלִידַת תְּרֵין צַדִּיקִים. וְהָכִי אִתְחֲזֵי, הָא שְׁמִטָּה, דְּבֵין תְּרֵי צַדִּיקֵי יָתְבָא לְעָלְמִין, דִּכְתִיב, (תהילים ל״ז:כ״ט) צַדִּיקִים יִירְשׁוּ אָרֶץ, צַדִּיק לְעֵילָא וְצַדִּיק לְתַתָּא. צַדִּיק לְעֵילָא, מִנֵּיהּ נָגְדָן מַיִין עִלָּאִין. צַדִּיק לְתַתָּא, מִנֵּיהּ נָבְעָא נוּקְבָא מַיָא לְגַבֵּי דְכוּרָא, בְּתִיאוּבְתָּא שְׁלִים. צַדִּיק מִסִּטְרָא דָא, וְצַדִּיק מִסִּטְרָא דָא, כְּמָא דִּדְכוּרָא לְעֵילָא יָתִיב בֵּין תְּרֵי נוּקְבֵי, הָכִי נָמֵי נוּקְבָא לְתַתָּא יָתְבָא בֵּין תְּרֵי צַדִּיקִי.

Rachel bore two righteous ones, and this was also in order, since the Sabbatical septennate is placed perpetually between two Righteous Ones, as it is written: “The righteous ones shall inherit the land” (Ps. 37, 29), one Righteous One on high and one below. From the one on high there is a flowing out of upper waters, and from the one below there is a reciprocal welling up of water from the female principle toward the male principle in a perfect ecstasy. There are thus a Righteous One on this side and a Righteous One on that side; and as the male principle ahove is situated between two female principles, so the female principle below is situated between two Righteous Ones.

Segment 3ג׳

וְעַל דָּא, יוֹסֵף וּבִנְיָמִין תְּרֵין צַדִּיקִין נִינְהוּ. יוֹסֵף זָכָה לְמֶהוֵי צַדִּיק לְעֵילָא, בְּגִין דְּנָטַר אָת קַיָּימָא. בִּנְיָמִין אִיהוּ צַדִּיק לְתַתָּא, לְאִתְעַטְּרָא שְׁמִטָּה בֵּין תְּרֵי צַדִּיקֵי, יוֹסֵף הַצַּדִּיק, וּבִנְיָמִין הַצַּדִּיק.

Hence Joseph and Benjamin represent the two Righteous Ones. Joseph merited to be the (symbol of the) Righteous One on high in virtue of his having kept under guard the sign of the holy covenant. Benjamin was the Righteous One below, so that the Sabbatical septennate was crowned between Righteous Ones, to wit, Joseph the righteous and Benjamin the righteous.
