Shabbos as intermediary and mutual testimony

אך את שבתותי תשמורו כו'.

"But (ach) you shall guard My Shabbosos…"

The posuk uses the limiting word "ach" (but/only) — the Sefas Emes will explain what this exclusionary word teaches about Shabbos.

חז"ל אמרו אך חלק.

Chazal said: "ach" (but) denotes a portion/division (chelek).

Chazal darshen the word "ach" as implying a "chelek" — that Shabbos itself is divided into portions, an upper part and a lower part.

דכתיב אות היא ביני וביניכם.

For it is written, "it is a sign (os) between Me and you."

Shabbos is called an "os" — a sign "between Me and between you" — language that places it as an intermediary between Hashem and Bnei Yisrael.

א"כ השבת הוא ממוצע.

If so, Shabbos is an intermediary (memutza).

Being a "sign between" the two, Shabbos stands as a memutza — a midpoint bridging the upper and lower worlds.

ויש בו חלק ברוחניות ובגשמיות.

And it contains a portion in the spiritual and a portion in the physical.

As an intermediary, Shabbos has two "portions": a spiritual (ruchniyus) dimension above and a physical (gashmiyus) dimension below.

כמ"ש בזוה"ק ויקהל בפסוק ושמרו בני ישראל את השבת ההוא רוחא אתפשטותא דההוא נקודה כו' אתענג מעילא ומתתא ע"ש ד' ר"ד ע"ב באורך.

As it says in the Zohar HaKadosh, Vayakhel, on the verse "and Bnei Yisrael shall guard the Shabbos" — "that spirit, the expansion of that point… delights from above and from below" — see there at length, daf 204b.

The Zohar describes Shabbos as a "point" (nekudah) whose spirit expands and "delights from above and from below" — drawing pleasure (oneg) into both the upper and lower realms, confirming its dual nature.

א"כ א"ש אך חלק.

If so, "ach" (denoting a portion) is well understood.

This explains Chazal's "ach chelek": the word fits perfectly, since Shabbos genuinely has an upper and a lower portion.

דזה החלק שלמטה צריך שמירה.

For this portion below requires guarding (shemirah).

The "ach" specifically limits and points to the lower, physical portion — for it is the earthly part of Shabbos that requires our shemirah (guarding).

וכן אומרים בתפלה פורס סוכת שלום עלינו.

And so we say in the tefillah, "He spreads (pores) a sukkah of peace over us."

The same idea appears in the bracha "pores sukkas shalom" — Hashem spreads over us a "sukkah of peace."

מלשון פרס וחלק שיש לנו בסוכת שלום.

From the language of "peras" (a portion) — the portion that we have in the sukkah of peace.

The word "pores" can be read from "peras/chelek" — a portion — hinting at the share of the "sukkah of peace" (Shabbos) that is given to us below.

וגם לפי הפשוט מאחר שהשבת הוא ברית א"כ הוא ממוצע בין עליונים לתחתונים ולכן נקרא שלום כי באמת עוה"ז מהופך מעולם העליון.

And also according to the simple meaning: since Shabbos is a covenant (bris), it is an intermediary between the upper and lower worlds, and therefore it is called "shalom" (peace), for in truth this world is the inverse of the upper world.

On a plain level too, Shabbos is a bris — a covenant — bridging upper and lower. It is called "shalom" because it reconciles two realms that are normally opposites: olam hazeh is, as it were, "upside down" relative to the upper world.

רק בשבת יש בו התאחדות לעליונים עם התחתונים ונק' יום מנוחה ושלום.

Only on Shabbos is there a unification of the upper with the lower, and it is called "a day of rest and peace."

Shabbos uniquely unites the upper and lower worlds, harmonizing the opposites — which is why it is called a day of "menuchah v'shalom," rest and peace.

לכן מצוה בשבת להתענג באכילה ושתי'.

Therefore it is a mitzvah on Shabbos to take pleasure (oneg) in eating and drinking.

Because Shabbos sanctifies even the physical, there is a mitzvah of oneg Shabbos through bodily pleasures of food and drink — the gashmiyus itself becomes holy.

וכ' קודש הוא להם.

And it is written, "it is holy for them."

The posuk "kodesh hu lachem" teaches that the day's kedushah extends even to "them" — to the physical enjoyment.

אפילו בגשמיות שורה הקדושה בשבת.

Even in the physical, kedushah rests on Shabbos.

Uniquely on Shabbos, holiness dwells even within material things — eating and drinking themselves become vessels of kedushah.

ואיתא בדרשות מהרי"ט ז"ל פי' ביני וביניכם כי כמו שבנ"י מעידין שהקב"ה ברא עולמו בו' ונח בשביעי וזה טעם כי בו שבת.

And it is brought in the Derashos of the Maharit, of blessed memory, the explanation of "between Me and you": that just as Bnei Yisrael testify that Hashem created His world in six (days) and rested on the seventh — and this is the meaning of "for on it He rested."

The Maharit explains the mutual "sign": by keeping Shabbos, Bnei Yisrael bear eidus (testimony) that Hashem created the world in six days and "rested" on the seventh.

כמו כן השי"ת מעיד על בני ישראל שכל העולם נברא רק בעבורם.

So too Hashem testifies concerning Bnei Yisrael that the entire world was created only for their sake.

The testimony is mutual: just as we testify about creation, Hashem testifies about us — that the whole world was created solely for the sake of Bnei Yisrael.

ולכן שינה הטבע ביצ"מ בעבורינו.

And therefore He changed nature at Yetzias Mitzrayim for our sake.

The proof of this testimony is that Hashem overturned the natural order at Yetzias Mitzrayim for Bnei Yisrael — showing the world exists for them.

וזה טעם כי עבד היית ע"ש בפ' ויקהל.

And this is the reason for "for you were a slave" — see there in Parshas Vayakhel.

This is why the version of the Shabbos mitzvah tied to "zachor… ki eved hayisa" recalls the Exodus: Shabbos testifies both to creation and to Hashem's special bond with Bnei Yisrael revealed in the Exodus.

[וכבר דברנו מזה במקומות אחרים רק כעת מצאתיו במהרי"ט ג"כ].

[And we have already discussed this in other places; it is only that now I found it in the Maharit as well.]

The Sefas Emes notes he has said this elsewhere and was glad to find the Maharit saying the same.

ולכן שבת סהדותא איקרי בכולא.

Therefore Shabbos is called "the testimony" in all (respects).

Hence Shabbos is universally called "sahadusa" — the testimony — bearing witness in both directions.

עדות בשמים על בנ"י ובארץ על הקב"ה.

Testimony in Heaven concerning Bnei Yisrael, and on earth concerning the Holy One.

Shabbos is a two-way eidus: in Heaven it testifies that the world exists for Bnei Yisrael, and on earth it testifies that Hashem created the world.

ואך את שבתותי תשמורו הוא עדות המסורה לנו שבזה כלול ג"כ החלק והעדות שלמעלה לכן כתיב אך חלק כנ"ל:

And "but you shall guard My Shabbosos" is the testimony handed over to us — and included within it is also the (upper) portion and the testimony above; therefore it is written "ach" (denoting a portion), as above.

Our task of "guarding" Shabbos is the portion of testimony entrusted to us below — yet by fulfilling it we also draw in the upper portion and testimony. Thus the word "ach" again signals the two portions: by guarding the lower part, we are bound to the higher part as well.

Summary: Shabbos is an intermediary that unites the upper and lower worlds, so it has two "portions" — a spiritual one above and a physical one below; the word "ach" points to the lower portion entrusted to us to guard, through which even physical enjoyment becomes holy. Shabbos is also a mutual testimony: by keeping it we attest that Hashem created the world, while He attests that the world was created for the sake of Bnei Yisrael, so that guarding our portion below draws in the testimony and portion above.
