The sacrifices in the Holy Temple created unification of upper light and the Shechina. One type was of vegetation (Wheat, barley), non-animal offering. The priests brought it to the altar, pour oil (Chokmah) on it and let it burn. The priests were told to eat the remnants of this offering. The offering was simple but on a higher spiritual level that only the priest and his sons could eat it.
Some other type of offerings brought by the people could be eaten and shared by those who brought them.
The Zohar compares the words of Torah students to the remnants of the offerings that were given to the priests.
The Torah studies create unifications of light and vessel and the students can benefit from it. Those who are dedicated to the Torah benefit as if their studies is the main offering, not the remnants of it. They are on a higher level.
“תָּקָם בְּעוֹד לַיְלָה וַתִּתֵּן טֶרֶף לְבֵיתָהּ וְחֹק לְנַעֲרֹתֶיהָ”
“She rises also while it is still night And gives food to her household And portions to her maidens.”
It’s like a king receiving gifts from his people. He ask them to send their gifts through the queen. The queen receives the gifts and shares them with all.
The above verse from Proverbs is where we find the song “Woman of Valor” that we sing on Friday night before the first meal of Shabbat. The ‘Woman’ is the Shechina and on Shabbat we call her ‘Queen’ because on Shabbat we elevate to Binah and the Queen is in unification with the ‘King’. Our Shabbat prayers and studies are like offerings that benefit us greatly and directly. The dinner table has the aspect of the Altar and the meal is the offering. We make Kiddush and blessings over the Challah, then we make Birkat Hamazon, which is the longer blessing over the meal. During the meal we read special Zohar text to elevate the ‘offering’ and receive gifts from the queen.
