Yom Kippur's atonement radiating through the year

ואל יבא בכל עת אל הקודש.

"And let him not come at all times into the holy place" (Vayikra 16:2).

The verse warns that the Kohen Gadol may not enter the innermost holy place at any time he wishes, but only on Yom Kippur. The Sefas Emes will draw from this a teaching about the unique power of that day.

מכאן אמרו חז"ל במקום שבעלי תשובה עומדין אין צדיקים גמורים יכולין לעמוד.

From here Chazal derived: "In the place where ba'alei teshuvah (penitents) stand, complete tzaddikim cannot stand."

The Sefas Emes connects the restricted entry of the verse to the famous teaching that ba'alei teshuvah reach a level even the wholly righteous cannot attain. He will explain how Yom Kippur embodies the aspect of teshuvah.

כי בכל השבתות וימים טובים א"י לכנוס לפני ולפנים רק ביוה"כ שהוא בחי' בע"ת שנפתח להם שער מעולם העליון.

For on all the Shabbosos and Yamim Tovim one cannot enter into the innermost chamber (lifnai v'lifnim) — only on Yom Kippur, which is the aspect of ba'alei teshuvah, when a gate is opened to them from the upper world.

Even the holiness of Shabbos and the festivals does not grant entry to the Holy of Holies; only Yom Kippur does. This is because Yom Kippur embodies the level of the ba'al teshuvah, for whom a special gate to the highest world — beyond the reach of even the tzaddik gamur — is opened.

וע"ז איתא במד' ה' אורי בר"ה וישעי ביו"כ.

And concerning this it is taught in the Midrash: "Hashem is my light" (Tehillim 27:1) — on Rosh Hashanah; "and my salvation" — on Yom Kippur.

The Midrash divides the verse between the two great days of judgment: "my light" refers to Rosh Hashanah, and "my salvation" (yeshu'ah) refers to Yom Kippur, indicating a distinct quality unique to Yom Kippur.

כי בר"ה נחתמין צדיקים גמורים לחיים אבל ביו"כ ישועה לכל העולם אפי' להחוטאים שהם צריכין ישועה.

For on Rosh Hashanah, complete tzaddikim are sealed for life; but on Yom Kippur there is salvation for the whole world — even for sinners, who are the ones in need of salvation.

Rosh Hashanah is "light" — the day on which the fully righteous are immediately sealed for life. But "salvation" specifically implies rescuing one who is in trouble; hence Yom Kippur, the day of yeshu'ah, reaches even sinners who need to be saved, which is precisely why it surpasses Rosh Hashanah.

ויום הזה הוא ישועה לכל השנה לבעלי תשובה.

And this day is salvation for the entire year for ba'alei teshuvah.

Yom Kippur is not a one-time event; it is a wellspring of salvation that radiates over the whole year for those who do teshuvah.

כמ"ש ביום הזה יכפר.

As it is written: "For on this day He shall atone [for you]" (Vayikra 16:30).

The Torah's phrasing "on this day" marks Yom Kippur as the source-point of atonement.

כי כל כפרות של כל השנה מיום הזה.

For all the atonements of the entire year flow from this day.

Whatever atonement a person attains at any point during the year ultimately draws from the reservoir of forgiveness opened on Yom Kippur.

וכ"כ אחת בשנה יכפר שזה היום מכפר בכל ימי השנה.

And so it is written, "once a year he shall atone" (Vayikra 16:34) — that this day atones throughout all the days of the year.

The Sefas Emes reads "once a year" not as limiting atonement to a single day, but as teaching that this one day's power of atonement extends its influence across every day of the year.

וכן דרשו חז"ל ימים יצרו ולו אחד בהם זה יו"כ וכתי' בהם.

And so Chazal expounded: "Days were formed, and to Him is one among them" (Tehillim 139:16) — this is Yom Kippur; and it is written "among them" [i.e., its influence is within all the days].

The verse speaks of one special day among all the days, which Chazal identify as Yom Kippur. The crucial word is "in them" (bahem): this one day is not separate from the rest but works within all the other days, infusing them with its power of atonement.

וכמו כן מה שדורש במדרש אורי וישעי בים מטעם הנ"ל שהי' אז ישועה לכל הדורות ויושע ה' ביום ההוא ולכן אומרים זה בכל יום.

And similarly, what the Midrash expounds — "my light and my salvation" with respect to the [splitting of the] sea — is for the same reason: that there was then a salvation for all generations, "and Hashem saved [Yisrael] on that day" (Shemos 14:30); and therefore we recite this every day.

The same principle explains the splitting of the sea: the salvation that occurred "on that day" was not confined to that moment but became a salvation for all generations. That is why the song of the sea is recited daily — the saving power of that day continues to flow into every day.

וגם מה שדרשו חז"ל ולו אחד בהם על יום השבת שהוא ג"כ ברכה על כל ימי השבוע:

And also what Chazal expounded, "and to Him is one among them," concerning the day of Shabbos — for it too is a blessing upon all the days of the week.

The same verse is also applied to Shabbos: like Yom Kippur, Shabbos is the "one day" whose blessing radiates into and sustains all the other days. The "one special day" — whether Yom Kippur, the day of the sea's splitting, or Shabbos — works "within them all," pouring its light and salvation into the entire span of ordinary time.

Summary: The Sefas Emes teaches that Yom Kippur embodies the aspect of teshuvah, opening a gate to the highest world that even the complete tzaddik cannot reach on Shabbos or Yom Tov — for "salvation" implies rescuing even the sinner. Like the splitting of the sea and like Shabbos, Yom Kippur is the "one day among them" whose atoning power is not confined to itself but radiates "within them all," pouring forgiveness, light, and salvation into every day of the entire year.
