137. אָמַר לוֹ, כֵּן, שֶׁהֲרֵי בְּאוֹתָהּ שָׁעָה לֹא הָיוּ לוֹ. [לְאַחַר שֶׁיָּצָא מִבֵּית הָאֲסוּרִים הָיוּ לוֹ] וְאִם תֹּאמַר, וּבְנֵי בִנְיָמִין בֶּלַע וָבֶכֶר, כְּשֶׁנִּכְנְסוּ לְמִצְרַיִם, כָּךְ זֶה וַדַּאי. שֶׁכָּל זְמַן שֶׁהִתְאַבֵּל יַעֲקֹב עַל יוֹסֵף, לֹא שִׁמֵּשׁ מִטָּתוֹ וְהוֹלִיד בָּנִים. וְאָמַר בִּנְיָמִין: הִנֵּה יוֹסֵף אָחִי, אוֹת הַבְּרִית שֶׁל אַבָּא הָיָה, שֶׁהֲרֵי הַבְּרִית הִיא סִיּוּם הַגּוּף. כֵּיוָן שֶׁהוּא נֶאֱבָד, אֲנִי אֶהְיֶה שׁוֹמֵר מְקוֹמוֹ שֶׁל אָחִי.
138. וְאִם תֹּאמַר, הֲרֵי בְּאוֹתוֹ זְמַן שֶׁנֶּאֱבַד לֹא הָיָה צַדִּיק, שֶׁצַּדִּיק הוּא לֹא הָיָה עַד שֶׁקָּרָה הַמַּעֲשֶׂה הַזֶּה בּוֹ – אֶלָּא כֻּלָּם הָיוּ יוֹדְעִים מִיַּעֲקֹב, שֶׁיַּעֲקֹב הָיָה יוֹדֵעַ שֶׁהַמָּקוֹם הַזֶּה יָרַשׁ יוֹסֵף, וּמִשּׁוּם כָּךְ הֶאֱרִיךְ אֵצֶל לָבָן כָּל כָּךְ, עַד שֶׁיִּסְתַּיֵּם הַגּוּף, וּמִי הוּא סִיּוּם הַגּוּף? הַבְּרִית, וְעַל כֵּן כָּתוּב וַיְהִי כַּאֲשֶׁר יָלְדָה רָחֵל אֶת יוֹסֵף וְגוֹ’. שֶׁהֲרֵי וַדַּאי כָּעֵת הִשְׁתַּלֵּם הַגּוּף. כֵּיוָן שֶׁהִשְׁתַּלֵּם הַגּוּף, אֲנִי רוֹצֶה לָלֶכֶת. וּמִשּׁוּם כָּךְ בִּנְיָמִין יָדַע וְשָׁמַר אֶת דֶּרֶךְ אָחִיו.


Zohar Vayetze
Continued from previous DZ
At that time, he (Benjamin) had no sons yet. And if you say, isn’t the Torah clear, “and the sons of Benjamin were Bela and Bechor” when they came to Egypt. Yes, by then, Benjamin already had children because as long as Jacob mourned for Yosef, he did not connect to his wife or bring children. Benjamin had in his mind that his brother Joseph was the connection to Yessod for his father because Jacob is Zeir Anpin, which includes Chessed, Gevurah, Tiferet, Netzach, Hod, and Yessod, and Joseph is the Yessod of Jacob, because Yessod is the end of the body, the reproductive organ. Since Joseph’s place is unknown, Benjamin took on himself to take his brother’s place and keep the purity of the channel of Yessod.

And if you say, at the time when Joseph was lost, Joseph was not yet considered a Tzadik because one cannot merit the level of Tzadik unless they are tested, and at that time, Joseph had not yet faced any test. The answer is that everyone knew this from Jacob, who knew that the level of Yessod would be inherited by Joseph, meaning he learned through the Holy Spirit that he would be tested in the incident with Potiphar’s wife and would merit the level of Tzadik (Yessod). That is why Jacob waited so long in Laban’s house and did not return to his own home until the body was completed, which is Yessod, Joseph. Therefore, it is written;
Genesis 30:25
“וַיְהִי כַּאֲשֶׁר יָלְדָה רָחֵל אֶת יוֹסֵף וַיֹּאמֶר יַעֲקֹב אֶל לָבָן שַׁלְּחֵנִי וְאֵלְכָה אֶל מְקוֹמִי וּלְאַרְצִי.”
“And it came to pass, when Rachel had borne Joseph, that Jacob said to Laban, “Send me away, that I may go to my own place and to my country.”
After Joseph has been born, the body, which is Tiferet, has been completed, and since the body is constructed, Jacob knew that he should go back to his land.
Jacob knew through the Holy Spirit that Joseph is Yessod, and everyone knew it from him. Therefore, Benjamin knew, and he followed his brother’s way; that is, he became the Tzadik (Yessod) for his father in place of Joseph after he was lost.
