Welcome to Daily ביטחון, a special Friday edition for שבת שובה.
We are going to start with the מדרש רבה on בראשית 22:13. The מדרש is talking about קין, stating that when he walked away from God, he departed like one attempting to deceive the Almighty—meaning his תשובה was not wholehearted. The next line of the מדרש continues: פגע בו אדם הראשון.
He met up with אדם הראשון, and אדם asked him, "So, what happened with your judgment?"
קין answered, "I repented and arrived at a compromise with God."
אדם then began to slap himself on the face and said, "Such is the power of תשובה, and I did not know?" Immediately, אדם arose and recited the מזמור in תהילים 92:1: מזמור שיר ליום השבת טוב להודות לה׳—"A song for שבת; it is good to thank השם."
Now, what exactly is going on here? What does this have to do with שבת?
מדרש number two, found in מדרש תנחומא (בראשית, פרק י׳), says that God placed an אות—a sign—upon קין to protect him. What was that sign? The מדרש תנחומא explains that it was שבת that protected him, as it says in שמות 31: ביני ובין ישראל אות היא לעולם—"Between Me and the children of Israel, it is an everlasting sign." The sign of protection was שבת itself. Just as שבת protected אדם, שבת protected קין.
This introduces a fascinating turn in the narrative. שבת protected אדם—perhaps אדם did not fully realize it at the time, because his punishment was delayed until מוצאי שבת due to the lingering אור הגנוז (the hidden light). So שבת was already working for אדם, and it worked for קין as well, and it seems אדם הראשון only fully grasped this through קין.
Regardless, how exactly is שבת a protection for קין? What did אדם הראשון see in קין's protection that made him realize, "Oh, if only I had known"?
The ספר עבודת ישראל on פרשת בראשית—authored by the קאזשניצער מגיד, רב ישראל האפשטיין (1737–1814), a student of the מגיד of מעזריטש and רב אלימלך of ליזענסק—addresses this with a question: What does it mean that קין was decreed to become a wanderer? Anyone can technically choose to stay wherever they want, so what forced him to wander?
The answer is that God placed within him an internal dread—a pervasive anxiety—such that he could never feel at peace wherever he was. The עבודת ישראל explains that if קין had been able to connect properly to הקדוש ברוך הוא, all these fears would have dissipated, and the harsh judgment would have been sweetened. But the curse itself was that his mind was clouded, preventing him from reconnecting to השם. True ביטחון involves cleaving (דבקות) to השם, and that cleaving is what shields a person. Because קין lacked that clarity, he lived in continuous fear and anxiety, constantly on the run.
Therefore, what protected him and mitigated his decree was שבת, because שבת granted him the capacity for מנוחה (rest). שבת brought inner peace. It enabled him to reconnect to הקדוש ברוך הוא, granting him a sense of reprieve. When אדם saw the power of שבת to bring מנוחה—which ultimately fosters דבקות—he was awestruck. He exclaimed: מזמור שיר ליום השבת, a song for the day that restores peace of mind. That is approach number one.
Approach number two comes from the חתם סופר on שבת שובה. He explains that when אדם met קין, אדם knew what the מדרש revealed: קין's תשובה was not wholehearted. Had it been wholehearted, he would have received complete forgiveness rather than a compromise. That is why אדם said, "I did not realize the power of תשובה"—he had not realized that even a flawed, incomplete תשובה brings atonement.
The ספר פרי צדיק (also on שבת שובה, אות י״ג) builds on this theme, citing a פסיקתא where the Jewish people ask, "If we do תשובה, will it be accepted?" God points to קין as proof.
Why would they question whether תשובה works? Doesn't the תורה explicitly teach that תשובה is accepted?
The answer is that they were unaware of this lower tier of repentance. They understood תשובה מאהבה (out of love) and תשובה מיראה (out of awe/fear), but they did not know about תשובה from יסורים (suffering)—the kind of repentance born after קין was battered by a miserable life. They did not realize that a self-interested תשובה, done simply to escape suffering, could still find favor. אדם הראשון had assumed the same: "Having been expelled from גן עדן, how could I turn around and do תשובה expecting השם to accept me?" Once he heard from קין that even this level works, he broke into the song of שבת.
Once again: what does this have to do with שבת?
Here we can turn to רב יעקב קמנצקי in the ספר אמת ליעקב. He asks: Why is this psalm titled מזמור שיר ליום השבת? The content does not overtly speak about שבת. It speaks of individuals facing deep adversity (אמונתך בלילות—faith in the dark nights); it speaks of the wicked flourishing; it addresses profound existential questions. What connects this to שבת?
Rav Yaakov explains through the מדרש that משה רבינו requested a day of rest for the Jewish people in Egypt. This is why we say ישמח משה במתנת חלקו ("Moshe rejoiced in the gift of his portion")—Moshe instituted שבת in מצרים, and God affirmed it as the holy day of rest. What did משה רבינו do on that day of rest? He wrote eleven scrolls of חיזוק, which correspond to the eleven chapters of תהילים authored by משה, beginning with תפילה למשה.
This מדרש is referenced in connection פרעה commanded that their workload be increased to prevent them from resting, precisely because he wanted to strip away their opportunity to study these scrolls and draw weekly encouragement that הקדוש ברוך הוא would redeem them.
The songs משה composed were geared specifically toward this message: even when you are broken in גלות, you can still return. Even if it is not מאהבה or מיראה, but merely ויאנחו—a cry stemming from sheer exhaustion and pain. As משה wrote in תהילים 90: תשב אנוש עד דכא—let man return even when crushed to the dust (דכא, meaning דכדוכה של נפש, a pounded spirit). Furthermore, the opening letters of מזמור שיר ליום השבת form the acronym למשה. How do we reconcile whether this מזמור was composed by משה or אדם הראשון? The מדרש in 22:13 explains that אדם הראשון originally uttered it, it was later forgotten, and משה רבינו restored it.
טוב להודות לה׳.
This brings us to a final, beautiful insight. The word להודות means to give thanks or praise, but its root is also identical to וידוי (confession). It is good to confess to השם on שבת.
Yet, how can that be, when formal וידוי is generally omitted on שבת?
The answer is that there are two forms of confession. The root י-ד-ה (as in מודה במקצת) means to admit. Saying "thank you" is an admission of dependence; it acknowledges that you are indebted to another. That is the הודאה of שבת. It is a distinct form of confession: realizing how much we receive from God, and recognizing how little we reciprocate. It is a confession framed not by self-flagellation, but by humbled gratitude.
As we enter שבת שובה, let us internalize the power of שבת.
Let us embrace שבת's ability to restore peace of mind so that we can reconnect to הקדוש ברוך הוא.
Let us recognize that even if we arrive battered by the exhaustion of the workweek, our תשובה is embraced. We find our day of rest, look back at a week of personal גלות, hard work, and endless השתדלות, and remember that שבת shares its root with לשוב—to return to God. We may be turning to שבת not only out of pure longing, but out of a desire to escape the weariness of the week. Even when we stand at the point of דכדוכה של נפש, bruised and exhausted, הקדוש ברוך הוא welcomes us back.
That is the essence of מזמור שיר ליום השבת. That is what אדם הראשון learned from קין: a person can return even under duress and distress. The same מדרש, in discussing תשובה born of suffering, cites King מנשה calling out to God from within a boiling cauldron, and King אחאב humbling himself under severe pressure—both of whom were accepted. Surely, then, God has an open door for us.
That is the true spirit of שבת שובה. הקדוש ברוך הוא yearns for our return, even when prompted by our hardships. He provided us with a day of מנוחה to restore our connection to Him, despite our missteps. אדם הראשון faltered on ראש השנה, and every year we work to repair that root. Through שבת שובה, we are handed the timeless lesson of אדם.
Take full advantage of this שבת. Have a שבת שלום, and בעזרת השם, may we all merit to achieve true תשובה.
