Shabbos and Torah share one essence

איתא בגמ' דכ"ע בשבת ניתנה תורה כתיב הכא זכור כו' יום השבת כו' וכ' התם זכור את היום כו' אשר יצאתם כו' בעצומו של יום כו'.

It is brought in the Gemara that according to all opinions the Torah was given on Shabbos. It is written here, "Remember (zachor) the Shabbos day" (Shemos 20:8), and it is written there, "Remember (zachor) this day on which you went out [of Mitzrayim]" (Shemos 13:3) — "on the very strength of the day (b'atzumo shel yom)."

The Gemara (Shabbos 86b) establishes through a gezeirah shavah, linking the word "zachor" in both verses, that the Torah was given on Shabbos. The Sefas Emes will build on this connection between Shabbos and Matan Torah.

א"כ נראה כי עצומו של יום מתן תורה הוא יום השבת.

If so, it appears that the very essence of the day of Matan Torah is the day of Shabbos.

The Sefas Emes infers that the inner essence — the "atzmus," the very core — of the day on which the Torah was given is identical to the essence of Shabbos itself.

כי במה שהי' במקרה ביום שבת לא שייך לומר זכור בעצומו של יום.

For regarding something that happened on Shabbos merely by chance, it would not be appropriate to say "remember the very essence of the day."

If the Torah had only happened to coincide with Shabbos incidentally, the language of "atzumo shel yom" — the intrinsic substance of the day — would not apply. The fact that the Torah speaks this way shows that Matan Torah and Shabbos share one inner essence; their meeting was no accident.

והענין הוא עפ"י מ"ש ז"ל בפסוק יום הששי למה הוסיף ה' תנאי התנה הקב"ה אם מקבלין ישראל התורה כו'.

The matter is understood according to what Chazal said on the pasuk "the sixth day" (Bereishis 1:31) — why did it add the letter hei? The Holy One, blessed be He, made a condition: if Bnei Yisrael accept the Torah [creation will endure, and if not, it will return to chaos].

Chazal note the extra "hei" (the definite article) on "the sixth day," which alludes to "the sixth" of Sivan, the day of Matan Torah. Creation was made conditional on Bnei Yisrael accepting the Torah — the world's very existence depends on it.

וכ' מקודם וירא אלקים כו' כל אשר עשה כו' טוב מאוד וזה החן קיים כל העולם ומזה נעשה השבת שהוא הנייחא שיש להקב"ה וב"ש מהבריאה במה שראה שעתידין בנ"י לקבל התורה שנקרא טוב.

And it is written beforehand, "And God saw all that He had made, and behold it was very good (tov me'od)" (Bereishis 1:31) — this favor (chein) sustains the entire world. And from this came about Shabbos, which is the contentment (nei'cha) that the Holy One, blessed be He, has from creation, in that He saw that Bnei Yisrael were destined to receive the Torah, which is called "good."

Hashem's seeing that creation was "very good" is the chein, the divine favor, that holds the world in existence — and what He saw as "good" was the future acceptance of the Torah, which Chazal call "good" ("a good acquisition"). Shabbos is the expression of Hashem's "rest" and contentment from creation, a contentment rooted precisely in this foreseen acceptance of the Torah.

נמצא כמ"ש בשבת הטעם כי בו שבת וזה הי' השלמת העולם כמ"ש רש"י מה הי' עולם חסר מנוחה באת שבת נגמרה המלאכה.

It emerges, as it is written regarding Shabbos, that the reason is "for on it He rested (shavas)," and this was the completion of the world, as Rashi writes: "What was the world lacking? Rest. Shabbos came and the work was complete."

Rashi explains that creation was not finished until Shabbos brought "menuchah" (rest); the world was lacking precisely that repose. Shabbos completed creation by adding the dimension of rest and contentment.

כן הי' ביום מתן תורה שזה השלמת העולם ממש והוא עיקר המנוחה והנייחא לפניו ית' וזה גמר הבריאה.

So too it was on the day of Matan Torah, which is the true completion of the world, and it is the essential menuchah and contentment before Him, blessed be He — and this is the consummation of creation.

Just as Shabbos completed creation by bringing rest, Matan Torah is the genuine completion of the world. The giving of the Torah is the deepest "menuchah" and divine contentment, the true purpose for which everything was made.

וכמו כן מצד התחתונים יום השבת הוא קיום ומנוחה של בנ"י שהוא החזרת הדברים לשורשם וזה עיקר הנייחא.

And likewise from the side of the lower beings, the day of Shabbos is the endurance and rest of Bnei Yisrael, which is the return of all things to their root — and this is the essential contentment.

Shabbos is not only Hashem's "rest"; from our side, it is the menuchah of Bnei Yisrael, in which all things return to their spiritual source (shoresh). This homecoming to the root is the true repose.

וזה הטעם השני של השבת דכתיב וזכרת כי עבד היית כו' פי' שהוציאנו לחירות להיות במקום מנוחה ושורשו זה הוא השבת שיש ממנוחה וחירות זה חלק בש"ק לכל איש ישראל לכן הוא מעין עוה"ב.

And this is the second reason for Shabbos, as it is written, "and you shall remember that you were a slave [in Mitzrayim]" (Devarim 5:15) — meaning that He brought us out to freedom, to be in a place of rest and its root. This is Shabbos, for from this menuchah and freedom every Jew has a portion on the holy Shabbos; therefore it is a foretaste of Olam Haba.

The two reasons given in the Torah for Shabbos — creation and the Exodus — converge. Yetzias Mitzrayim freed us to reach a "place of rest," our root. Every Jew receives a portion of that menuchah and freedom each Shabbos, which is why Shabbos is "a taste of the World to Come."

ועיקר מנוחה זו ג"כ נתקיים ביום מתן תורה שאז הי' התדבקות כל נפש ישראל בשורש השייך לו וזה עיקר המנוחה כמ"ש אנכי ה' אלקיך אשר הוצאתיך כו':

And the essence of this menuchah was likewise fulfilled on the day of Matan Torah, for then every soul of Yisrael cleaved (hisdabkus) to the root that belongs to it — and this is the essential menuchah, as it is written, "I am Hashem your God, who took you out [of the land of Mitzrayim]" (Shemos 20:2).

At Matan Torah, every Jewish soul attained deveikus to its own particular spiritual root — the ultimate "rest." The first of the Aseres HaDibros, which links Hashem to the Exodus, expresses this: the freedom of Yetzias Mitzrayim culminates in the soul cleaving to its source through the Torah, which is the true menuchah of Shabbos.

Summary: Through the shared word "zachor," the Gemara teaches that the Torah was given on Shabbos — not by chance, but because Shabbos and Matan Torah share one inner essence. Shabbos completed creation by bringing menuchah, and Hashem's contentment with the world was rooted in His foresight that Bnei Yisrael would accept the Torah. So too Matan Torah is the true completion of the world, the deepest divine contentment, in which every Jewish soul cleaves to its root. This is the essence of Shabbos's menuchah — uniting the themes of creation and the Exodus — making Shabbos a foretaste of Olam Haba.
