Untouched Core Of Yisrael
בפסוק לא הביט און כו'
Regarding the pasuk, "He has not looked upon iniquity in Yaakov" (Bamidbar 23:21).
The Sfas Emes opens with Bilam's words that Hashem perceives no iniquity in Yaakov, setting up the central question of the piece.
פירשו חז"ל שאין מביט בעבירות שלהם וקשה אדרבא הקב"ה מדקדק עם הצדיקים כחוט השערה
Chazal explained that Hashem does not gaze upon their transgressions; yet this is difficult, for on the contrary, the Holy One, Blessed is He, is exacting with the tzaddikim to a hairsbreadth.
Chazal read the pasuk to mean Hashem overlooks their sins, but this seems contradicted by the principle that Hashem judges tzaddikim with the utmost precision.
אבל הענין הוא כי בכלל יעקב וישראל לא הביט און כי אין החטא נוגע לבחי' יעקב וישראל כמו שביקש יעקב אע"ה בקהלם אל תחד כבודי
But the matter is thus: within the very entity of "Yaakov" and "Yisrael" He has not looked upon iniquity, for sin does not touch the aspect of Yaakov and Yisrael, as Yaakov Avinu requested, "In their assembly let my honor not be joined" (Bereishis 49:6).
He resolves it: "Yaakov" and "Yisrael" name an inner aspect of Bnei Yisrael that sin cannot reach at all, the very holiness Yaakov asked not be implicated in any wrongdoing.
וזה הכח של יעקב וישראל שיש בכללות בנ"י לא נפגם לעולם אכן החוטא נסתלק ממנו מקודם הארת הקדושה שיש בו מכלל יעקב וישראל
And this strength of Yaakov and Yisrael, which resides in the entirety of Bnei Yisrael, is never blemished; rather, the one who sins has the illumination of the kedushah that is within him, drawn from the collective of Yaakov and Yisrael, depart from him beforehand.
This collective core of holiness is permanently untouched; when a person sins, it is not that the core is stained, but that his share of that illumination withdraws from him first.
ואמת גם זה הפי' כי האון והעמל לא הביטו ביעקב וישראל ומה"ט הקב"ה לא הביט ביעקב וישראל עמל ואון והכל אחד הוא
And this explanation too is true: that the iniquity and the toil did not look upon Yaakov and Yisrael, and for this reason the Holy One, Blessed is He, did not look upon toil and iniquity in Yaakov and Yisrael, and it is all one matter.
A second true reading: iniquity and toil themselves cannot fasten onto the aspect of Yaakov and Yisrael, so Hashem likewise sees none there, both readings amounting to the same truth.
ולכן אותו הרשע לא [*הי'] יכול לקללם כי כל כחו הי' כשמצא איזה תקלה שעתיד להיות הי' בו כח לחול הקללה בכח מה שהי' רואה וכן ראה בראש הפסגה שעתידין להכשל כו' אבל בנ"י אפילו מחשבה של חטא אין נחשב להם כמעשה
And therefore that rasha was unable to curse them, for his entire power lay in this: when he found some future stumbling that was destined to occur, he had the power to bring the curse to rest by force of what he saw, and so he gazed from the top of the peak that they were destined to stumble; but for Bnei Yisrael, even a thought of sin is not reckoned to them like a deed.
Bilam could only curse by latching onto a real future flaw he perceived, but since Bnei Yisrael's mere thought of sin does not count as a deed, he found no foothold in their essential core.
והטעם שאין החטא שלהם בעצם ואדרבא כשנכשלין בחטא מסתלק מקודם חלק הנשמה שבהם
And the reason is that their sin is not intrinsic to them; on the contrary, when they stumble in sin, the portion of the neshamah within them departs beforehand.
Sin is never part of their essence; the moment they fall, the neshamah-portion lifts away before the act, so the sin never adheres to who they truly are.
ונמצא בעוד כח הנשמה בהם אין בהם רושם חטא ולכן לא הי' שולט הקללה בהם כמ"ש ה' אלקיו עמו כו':
It thus emerges that so long as the strength of the neshamah is within them, there is no imprint of sin upon them, and therefore the curse had no dominion over them, as it is written, "Hashem his God is with him" (Bamidbar 23:21).
As long as the neshamah's strength remains within them, no trace of sin marks them, which is why the curse could gain no hold, for "Hashem his God is with him."
Summary: The Sfas Emes wrestles with Chazal's reading that Hashem looks upon no iniquity in Yaakov, given that Hashem is in fact exacting with tzaddikim to a hairsbreadth. He resolves this by distinguishing the inner aspect called "Yaakov" and "Yisrael" within the collective of Bnei Yisrael, a core of kedushah that sin can never touch or blemish. When a person sins, that core is not stained; rather his share of its illumination, his neshamah-portion, withdraws from him beforehand, so the sin never adheres to his true self. This is precisely why Bilam could not curse them: his power depended on fastening a curse onto a perceived future flaw, but in Bnei Yisrael even a thought of sin is not reckoned as a deed and leaves no imprint on the essential neshamah. As long as the neshamah's strength remains, no trace of sin marks them, and so, "Hashem his God is with him," the curse held no dominion.
