Sukkah and separation unto Hashem

סוכות הוא רמז למ"ש לכתך אחרי במדבר.

Sukkos is an allusion to that which is written: "your following after Me into the wilderness."

The mitzvah of Sukkah recalls Bnei Yisrael's willingness to follow Hashem into the uninhabited desert, trusting Him completely with no visible support.

והוא מדריגת אברהם אע"ה שכתוב בו לך לך מארצך כו'.

And this is the madreigah (level) of Avraham Avinu, of whom it is written: "Go forth from your land…"

This same trait of leaving everything familiar to follow Hashem was first embodied by Avraham, who went out at Hashem's word to an unknown land.

ובמד' שמעי בת וראי כו' שראה בירה דולקת תאמר שעוה"ז בלי מנהיג הציץ עליו הקב"ה אני הוא בעל הבירה.

And in the Midrash: "Listen, daughter, and see…" — like one who saw a palace lit up (or aflame); would you say this world has no Director? The Holy One looked out upon him: "I am the Master of the palace."

The Sefas Emes cites the famous mashal of Avraham: seeing the world's order ("a palace lit up") he refused to believe it was leaderless, and Hashem revealed Himself as the "Master of the palace" — the recognition of Hashem's kingship over creation.

כמו כן בכלל ישראל ר"ה ויוהכ"פ שמעי בת וראי.

So too with Klal Yisrael as a whole: Rosh Hashanah and Yom HaKippurim are "Listen, daughter, and see."

What Avraham experienced individually, the nation relives each year on the Yamim Noraim — a summons to recognize Hashem as Master and King of the world.

ומתפללין בנ"י תן פחדך כו' וידע כל פעול ומתמיהין על שנעלם כבוד מלכותו בעוה"ז.

And Bnei Yisrael pray "Instill Your awe…" and "let every formed being know," wondering with astonishment that the glory of His kingship is hidden in this world.

In the Rosh Hashanah tefillos we beg that all creation come to recognize Hashem's sovereignty, expressing our amazement and pain that His royal glory remains concealed in olam hazeh.

והתשובה שכחי עמך ובית אביך והוא מצות הסוכה שבנ"י מתפרשין מכל האומות.

And the answer is "forget your people and your father's house" — and this is the mitzvah of the Sukkah, in which Bnei Yisrael separate themselves from all the nations.

The resolution to that hiddenness is the Sukkah: by leaving their homes to dwell apart under Hashem's protection, Bnei Yisrael "forget" the surrounding nations and bind themselves to Hashem alone, just as the verse bids the bride to forget her former house.

ויתאו המלך יפיך.

"And the King will desire your beauty."

When Bnei Yisrael set themselves apart for Hashem, He cherishes their beauty — the verse's promise that follows "forget your people."

שכל מה שברא הקב"ה כל האומות.

For all that the Holy One created — all the nations —

The Sefas Emes now explains why the other nations exist at all in Hashem's plan.

הגם שראה שלא יזכו.

even though He foresaw that they would not merit —

Hashem knew in advance that the nations would not rise to true closeness with Him.

רק כדי להיות ניכר שבחן של בני ישראל כשושנה בין החוחים:

[He created them] only so that the praise of Bnei Yisrael should become recognizable, like a rose among the thorns.

The nations serve as a backdrop against which the distinctiveness and beauty of Bnei Yisrael shines — "like a rose among the thorns" — which is precisely revealed through the separation of the Sukkah.

Summary: Sukkos expresses the trait of Avraham — following Hashem into the wilderness and recognizing Him as Master of the world; the Yamim Noraim are Klal Yisrael's "Listen and see," and the Sukkah is the answer to Hashem's hidden kingship, for by separating from the nations and dwelling under His protection, Bnei Yisrael's beauty is revealed like a rose among the thorns.
