Galus redeems the holy sparks

בענין שמיעת יתרו אחר יצ"מ.

Regarding the matter of Yisro's hearing [and coming] after Yetzias Mitzrayim (the Exodus from Egypt).

The Sefas Emes addresses why the Torah records that Yisro heard of the miracles and came to join Bnei Yisrael specifically after the Exodus.

נראה כי זה הי' שכר הגלות כמ"ש ז"ל לא גלו ישראל אלא כדי שיתוספו עליהם גרים.

It appears that this was the reward of the galus (exile), as Chazal said: "Yisrael was exiled only in order that geirim (converts) be added to them" (Pesachim 87b).

Yisro's joining was the fruit of the Egyptian exile; one purpose of galus is to draw in righteous converts who attach themselves to Klal Yisrael.

ולכן בכח גלות מצרים הוציאו ערב רב.

Therefore, through the power of the Egyptian exile, they brought out the erev rav (mixed multitude).

The galus of Mitzrayim accomplished the extraction of the erev rav, those gentiles who left Egypt together with Bnei Yisrael.

ויתרו על כולם.

And Yisro above them all.

Yisro was the greatest of the converts drawn in through the exile, surpassing all the others.

ובזה נתקיים בכל עצב יהי' מותר.

And through this was fulfilled "in all toil there is profit" (Mishlei 14:23).

The painful "toil" of galus yields a profit — the geirim like Yisro who emerge from it; suffering is not in vain but produces lasting gain.

וזה הרמז ואהבתם את הגר כי גרים הייתם בארץ מצרים שתכלית הגלות הי' בעבור הגרים.

And this is the hint in "and you shall love the ger, for you were gerim in the land of Egypt" (Devarim 10:19) — that the purpose of the exile was for the sake of the geirim.

The Torah links our love for converts to our own exile in Egypt precisely because the very purpose of that galus was to produce geirim; we were "strangers" there in order to draw out the strangers who would join us.

ויתכן שזה רמזו חז"ל באמרם קשין גרים לישראל כספחת.

And it is possible that this is what Chazal hinted when they said: "geirim are as hard for Yisrael as a sapachas (a skin affliction)" (Yevamos 47b).

The Sefas Emes reinterprets the difficulty of converts: it is "hard" not because the geirim themselves are a burden, but because of what their ingathering requires.

שצריכין להתערב בין האומות בעבור הגרים.

For [Yisrael] must become intermingled among the nations for the sake of the geirim.

The "hardness" is the galus itself: in order to gather in the converts and the holy sparks among the nations, Bnei Yisrael must endure being scattered and mixed among them.

ולכן כ' חז"ל שחת ספחת בהרת צרעת נגד ד' מלכיות ע"ש במדרש שכל הד' גליות הוא כדי להוציא הניצוצי קדושה שמעורבין בסט"א.

Therefore Chazal wrote that "se'eis, sapachas, baheres, tzara'as" (the skin afflictions, Vayikra 14:56) correspond to the four kingdoms — see the Midrash — for all four exiles are in order to bring out the nitzotzei kedushah (holy sparks) that are intermingled within the sitra achra (the side of impurity).

The four types of skin affliction parallel the four galuyos. Just as the geirim are called a "sapachas," each exile is a painful affliction whose purpose is to extract the holy sparks trapped within the impure nations.

וע"י הגלות מתבררין ועולין.

And through the exile they are refined and rise up.

The very dispersion of Bnei Yisrael among the nations is what allows these holy sparks to be sifted out (birur) and elevated back to kedushah.

ובמדרש ה' עוזי ומעוזי ומנוסי ביום צרה אליך גוים יבאו כו'.

And in the Midrash: "Hashem, my strength (uzi) and my stronghold (ma'uzi) and my refuge (menusi) in the day of trouble, to You the nations will come" (Yirmiyahu 16:19).

The Sefas Emes brings a pasuk that lists three terms of strength and then states that the nations will ultimately come to Hashem — connecting the three terms to the ingathering of the geirim from the nations.

פי' שיש לבנ"י כל אלה המדרגות.

Meaning that Bnei Yisrael possess all these madreigos (levels).

The three terms — uzi, ma'uzi, menusi — correspond to three distinct levels within the avodah of Klal Yisrael.

כי עצם בנ"י הם דבקין בו יתברך ובתורתו.

For the essence of Bnei Yisrael is that they are attached to Him, may He be blessed, and to His Torah.

The first and highest level is the intrinsic deveikus of Bnei Yisrael to Hashem and His Torah — their essential bond, untouched by the world.

ומ"מ צריכין לתקן גם בעוה"ז הגשמיי בכח המצות שיש בהם אור תורה.

Nevertheless, they must also rectify this physical world through the power of the mitzvos, in which there is the light of Torah.

The second level is the avodah of tikkun in the material world, accomplished through mitzvos that carry within them the or haTorah, drawing kedushah into physical reality.

וצריכין ג"כ לכנוס במצרים כדי לתקן גם הני"ק שנמצא שם.

And they also need to enter into Mitzrayim in order to rectify the holy sparks (nitzotzei kedushah) that are found there.

The third level is descending into galus — into Egypt and the realm of impurity itself — in order to redeem the holy sparks trapped there, like Yisro and the converts.

והם ג' בחי' עוזי ומעוזי ומנוסי כו':

And these are the three aspects: uzi, ma'uzi, and menusi.

The three levels — essential deveikus to Hashem, rectifying the world through mitzvos, and descending into exile to redeem the sparks — correspond to "my strength, my stronghold, and my refuge in the day of trouble."

Summary: Yisro's coming to join Bnei Yisrael after the Exodus reveals the deeper purpose of galus: exile exists in order to draw in righteous converts and to extract the holy sparks intermingled within the nations. This is why "geirim are hard as a sapachas" — not because the converts burden us, but because gathering them requires the painful scattering of Yisrael among the nations, paralleled in the four afflictions corresponding to the four exiles. The pasuk "uzi, ma'uzi, menusi" maps three levels of avodah: the essential deveikus of Bnei Yisrael to Hashem, rectifying the physical world through the light-bearing mitzvos, and descending into exile itself to redeem the holy sparks trapped there.
