125 - And Moshe Said Eat It Today Because Today Is Shabbat to G-d

And Moshe said eat it today because today is Shabbat (Shabbat [Sabbath]) to G-d etc. (Exodus 16:25) And our rabbis learned of blessed memory (Shabbat 117b). From here, that one is obligated to eat three meals on Shabbat because three "today" are written [i.e., "today" appears three times in the verse] it is found that on every meal of the three meals of Shabbat is written today to hint not to eat in the meal of Shabbat only for that which is proper for the day [not for leftover hunger or future hunger, but for the holiness of the present moment] because sometimes he eats because he is hungry from yesterday and sometimes because he will not be hungry tomorrow but in every meal of the three meals of Shabbat he should not eat except for the day that is this meal not for before and not for after.

[This matter I did not hear from his holy mouth himself, only from the mouth of another who said in his name, and I wrote it as I heard. After that it happened that I spoke with him, of blessed memory, from this matter, and he doubted himself on this]

And he said: behold the eating of Shabbat is very precious very [extremely valuable] and as explained in all the words of our rabbis of blessed memory that on Shabbat one needs precisely to eat and to drink and to increase in delicacies [this reinforces the idea that Shabbat meals are spiritually elevated] and I understood that his intention in this above statement, is not to diminish in the eating of Shabbat, G-d forbid [he wasn't discouraging abundant Shabbat eating] and the content of his intention in this statement he did not explain to me at all because I did not merit to speak with him more from this statement only after that we heard from his holy mouth of blessed memory several several Torahs on the matter of the advantage of the holiness of the eating of Shabbat that is very precious and he said explicitly that one needs on Shabbat to increase in food and drink literally because the eating of Shabbat is all divinity all holy etc.

see in the Torah they asked Rabbi Yossi ben Kisma in section 57, and below [in section 277] what is written there that the main honor of Shabbat is the eating see there and more in several places [i.e., multiple sources affirm the value of eating on Shabbat] and see Sefer Nagid U'Mitzvah to the Arizal and so in Mishnat Chasidim that wrote explicitly that even though he eats on Shabbat more than the need he does not go to the externals like on weekday but is absorbed in the limbs [the physical act of eating on Shabbat is sanctified and internalized, unlike weekday eating]
