Moses represented Zeir Anpin and the Sun. Joshua, who served Moses was the aspect of the moon and could channel some of Moses’s Light to the nation.
As we studied in previous DZ, Moses, Aaron and Miriam were the great channels of Light for the Israelites. They led them out of Egypt and sustained them in the wilderness during the journey to the Promised Land.
“ וַיֹּאמֶר אֲלֵהֶם, בֶּן-מֵאָה וְעֶשְׂרִים שָׁנָה אָנֹכִי הַיּוֹם–לֹא-אוּכַל עוֹד, לָצֵאת וְלָבוֹא; וַיהוָה אָמַר אֵלַי, לֹא תַעֲבֹר אֶת-הַיַּרְדֵּן הַזֶּה.”
“And he said to them, “I am 120 years old today. I am no longer able to go out and come in. YHVH has said to me, ‘You shall not go over this Jordan.’”
Miriam, the middle sister, passed away first, then the older brother Aaron, then Moses.
When Moses was taken by God, the direct light of the ‘Sun’, Zeir Anpin, was also taken and only the ‘moon’, Joshua, could channel the light and lead the people into the Land.
Moses was the main tool of God in bringing the first redemption. He channeled the great Light of Zeir Anpin that was fully revealed when the Israelites left Egypt. We celebrate that night as the Seder in the holiday of Passover.
Moses, in the above verse, tells the nation that he is no longer able to go out and come in. The deeper meaning is that God didn’t allow him to make higher connection for the people. He could not channel the Light of Zeir Anpin for the people.
Moses did ‘go out’ of Malchut and elevate himself to the Sefirah of Da’at to bring for us the Torah, which is our weekly connection to Zeir Anpin.
Moses didn’t finish his Job and he keeps coming to us in every generation. He taught Rabbi Shimon the secrets of the Zohar and provides us with a taste of the Light of the ‘sun’. At the time of the Final Redemption Moses will open the gates of Da’at and usher Mashiach to the world. Then we’ll see the fulfillment of the prophecy of Isaiah 30:26
“ וְהָיָה אוֹר-הַלְּבָנָה, כְּאוֹר הַחַמָּה, וְאוֹר הַחַמָּה יִהְיֶה שִׁבְעָתַיִם, כְּאוֹר שִׁבְעַת הַיָּמִים–בְּיוֹם, חֲבֹשׁ יְהוָה אֶת-שֶׁבֶר עַמּוֹ, וּמַחַץ מַכָּתוֹ, יִרְפָּא”
“Moreover, the light of the moon will be as the light of the sun, and the light of the sun will be sevenfold, as the light of seven days, in the day when YHVH binds up the brokenness of his people, and heals the wounds inflicted by his blow.”
May we all see this happens in our days, Amen.
