445. We have learned that all blessing from above and from below depend upon the seventh day, and we have also learned that there was no manna on the seventh day because all the six supernal days - WHICH ARE CHESED, GVURAH, TIFERET, NETZACH, HOD AND YESOD - derive their blessing from it, and each of them sends forth nourishment to the world below from the blessing it received from the seventh day.
445. אֶלָּא הָכִי תָּאנָא, כָּל בִּרְכָּאן דִּלְעֵילָּא וְתַתָּא, בְּיוֹמָא שְׁבִיעָאָה תַּלְיָין. וְתָאנָא, אֲמַאי לָא אִשְׁתְּכַח מָנָּא בְּיוֹמָא שְׁבִיעָאָה, מִשּׁוּם דְּהַהוּא יוֹמָא, מִתְבָּרְכָאן מִינֵּיהּ כָּל שִׁיתָא יוֹמִין עִלָּאִין, וְכָל חַד וְחַד יָהִיב מְזוֹנֵיהּ לְתַתָּא, כָּל חַד בְּיוֹמוֹי, מֵהַהִיא בְּרָכָה דְּמִתְבָּרְכָאן בְּיוֹמָא שְׁבִיעָאָה.
