Segment 1א׳

תָּא חֲזֵי, דְּהָכִי אוֹלִיפְנָא מִסִּפְרָא דְּרַב הַמְנוּנָא סָבָא, וְהָכִי הוּא. כְּתִיב גַּדֵּל פֶּרַע שְׂעַר רֹאשׁוֹ, בָּעֵי דְּיִּתְרְבֵּי שְׂעַר רֵישֵׁיהּ וְדִיקְנֵיהּ, וְיִתְפְּרִשׁ מִיַיִן וְשֵׁכָר וַעֲנָבִים, בְּגִין דְּכֻלְּהוּ סְטָר שְׂמָאלָא, וְלָא תַּלְיָין שַׂעֲרָא. יַיִן אִימָּא עִלָּאָה. שֵׁכָר סִטְרָא דַאֲחִידוּ בֵּיהּ לֵיוָאֵי וְנַפְקֵי מִיַיִן עִלָּאָה וְלָא תָּלֵי שַׂעֲרָא. וּבְגִין כָּךְ כַּד סְלִיקוּ לֵיוָאֵי לְהַהוּא אֲתָר, בָּעֲיָין לְאַעְבְרָא כָּל שַׂעֲרָא דִּלְהוֹן, כְּמָה דְאַתְּ אָמֵר (במדבר ח׳:ז׳) וְהֶעֱבִירוּ תַעַר עַל כָּל בְּשָׂרָם. (קכ"א ע"ב).

The Book of Rab Hamnuna the Elder supports this exposition. There we read in reference to the injunction, he shall let the locks of hair of his head grow long, that the letting of the hair of his head and beard grow long and the abstention from wine and strong drink and grapes is for the reason that all these belong to the left side and they are, moreover, unhairy: the wine is the Superior Mother, the strong drink is a product of the wine and is unhairy. It belongs to the region of the Levites, and hence the Levites were enjoined to “cause a razor to pass over all their flesh” (Num. 8, 7).

Segment 2ב׳

עֲנָבִים אִימָּא תַּתָּאָה, דְּכָנִישׁ יַיִן וְשֵׁכָר לְגַוָּוהּ, וְעַל דָּא אִתְפְּרַשׁ מִכָּל סְטָר שְׂמָאלָא, דְּלָא לְאַחֲזָאָה עוֹבָדָא דִּילְהוֹן לְגַבֵּיהּ. עֲנָבִים דָּא לָא תָּלֵי שַׂעֲרָא וְדִיקְנָא. דְּהָא נוּקְבָּא בַּעְיָיא לְסַפְּרָא שַׂעֲרָא, כַּד אַתְיָא לְאִזְדַּוְּוגָא בִּדְכוּרָא, וְהָא דִּיקְנָא לָא אִשְׁתְּכַח בָּהּ. בְּגִין כָּךְ הוּא תָּלֵי שַׂעֲרָא דְּרֵישָׁא וְדִיקְנָא, וְרָזָא דְּמִלָּה (שופטים י״ג:ה׳) נְזִיר אֱלֹהִים אִקְרֵי, וְלָא נְזִיר יְיָ, פָּרִישׁ מִדִּינָא כֹּלָּא.

The grapes are the Lower Mother, which gathers in herself both the wine and the strong drink. The Nazirite therefore has to abstain from the whole of the left side, so that none of their works should be seen in him. And the grapes grow no hair nor beard, symbolic, as it were, of the female, who has to remove her hair before having relations with the male, and who is by nature beardless. Hence the Nazirite has to let grow his hair, including his beard.
