There is a Possuk in the book of Yoel that states; “And you shall eat, [in plenty] (eating) and be satiated ... and My people shall never be ashamed.” There is a well-known Maamor on this Possuk in Likkutei Torah at the beginning of the section dedicated to Maamorim on this week’s Parsha.
[The study of these Maamorim is otherwise referred to as the Chassidishe Parsha as the Frierdiker Rebbe’s famous saying: “In addition to the Parsha of the week in the ‘written Torah’ there is the Parsha of the week in Torah Ohr and in Likkutei Torah (both of which are Maamorim from the Alter Rebbe and are really two volumes from the same book as is explained in the Frierdiker Rebbe’s famous letter). They are Chassidic discourses based on the Parsha of the week.]
The Maamor in Likkutei Torah highlights the double expression in this Possuk of וַאֲכַלְתֶּם אָכוֹל and suggests that it implies that there are two eating sessions: first the אָכוֹל and then the additional וַאֲכַלְתֶּם. The connection to our Parsha (Parshas Tzav) becomes understood when in the continuation of the Maamor he brings a Medrash from Vayikroh Rabboh on the Possuk in our Parsha: זֶּה קָרְבַן אַהֲרֹן “This is the offering of Aharon” about which the Possuk states: וַיֹאמֶּר לָהֶּם מֵהָאֹכֵל יָצָא מַאֲכָל כוּ׳ “And he said to them, 'From the eater came out food',” in other words, Aharon eats from all the ‘Korbonos’ and now from him comes a Korbon. To which Korbon does this refer? “This is the offering of Aharon.”
In other words, even in this aspect of Aharon’s Korbon there is a double eating session; we need to understand this concept. This is because with eating in general there are two aspects; one is that the food elevates the person, for this reason it is specifically when a person eats food that he [continuously] connects his Neshomoh to his body. Secondly, by eating the food he thus refines the food, because as a result of partaking of the inanimate, the vegetative, or of the animal creations; he refines and purifies them, elevating them to become blood and flesh, [thus] part of the person’s (otherwise referred to as the ‘speaker’ [MeDaber] who is eating’s) very being.
Furthermore as a result of the speaker [MeDaber] who ate the food now going on to serve HaShem as the Talmudic maxim: “I, was created to serve the One Who formed me” the food thus ascends to a higher spiritual level; to a level which is higher than the world of creations because “Yisroel and HaKodosh Boruch Hu are one.”
It is about this, that the Possuk states: וַאֲכַלְתֶּם אָכוֹל because after the eating, the refining and the purification ... there still remains a greater aspect to be elevated; that which is being refined and ascends even higher and it is for this reason that there is yet another aspect of eating which constitutes a further refinement.
Because this Possuk alludes to the revelations of the future, post completion of the Avodah of this era when the first [level of] refinement will be complete, the Chiddush of the future will be that all the refinements achieved up until that time will have an automatic elevation to a level which is beyond comparison to the place from which they come. This refers to the second refinement.
As it has been explained regarding the Possuk וְשַבְתִּי בְשָלוֹם אֶּל בֵית אָבִּי וְהָיָה ה׳ לִּי לֵאלֹקִּים “And if I return in peace to my father's house, and HaShem will be my G-d” the spiritual level of Havaya today will be considered as a level of ‘Elokim’ in the future, and there will be a need for a refinement to a greater spiritual level which is the upper Havaya.
This is so because the current Avodah of Birur is the Avodah which refines the Divine name ‘Ban’ through the Divine name ‘Mah’, whereas in the future when Moshiach comes there will be an elevation within the Divine name ‘Mah’ [itself]. This then is the meaning of the [second expression of the] Possuk ׳וֹ וַאֲכַלְתֶּם אָכוֹל וְשָבוֹעַ וְג “And you shall eat,
