Ancestral Roots of Deeds
בפסוק ומלאו בתיך כו' אשר לא ראו אבותיך כו' עד היום הזה.
In the verse: “And your houses will be filled… such as your fathers have never seen… until this day.”
The Sefat Emet notes that this plague involved something unprecedented even for the ancestors, demanding explanation of what “your fathers have never seen” means.
פרשנו כבר כי אבותיו של הרשע רואין אחר מיתתם בגיהנם בעונש הבנים.
We have already explained that the ancestors of a wicked person see, after their own death in Gehinnom, the punishment of their descendants.
This introduces the principle that suffering of children is shown to wicked ancestors as part of their own judgment.
ונראה לבאר הענין דהמדה בבנ"י הוא שכשיש להם שמחה. הקב"ה מביא לאב ואם להיות להם חלק בשמחת בניהם.
It seems we may explain the matter: the measure for Israel is that when they have joy, God brings the father and mother to have a share in their children’s joy.
For the righteous, divine compassion includes allowing ancestors to partake spiritually in the joy of their descendants.
כדאיתא בזוה"ק בלק על פסוק ישמח ישראל בעושיו. שבנ"י מחזירין השמחה לשמים.
As stated in the Zohar (Balak) on the verse “Israel shall rejoice in its Maker,” that Israel returns their joy upward to Heaven.
Joy becomes elevated, connecting earthly celebration with divine realms.
ולכן הקב"ה משמח לאבותיהם.
Therefore God brings joy also to their ancestors.
The overflow of joy spreads backward through generations.
אבל כשיש ח"ו יסורים וצער לבנ"י. אין הקב"ה מראה לאבותיהם רק עמו אנכי בצרה ע"ש.
But when Israel, Heaven forbid, suffers pain or affliction, God does not show this to their ancestors—only “I am with him in distress.”
The suffering is not extended to righteous ancestors; it remains borne only by God, so to speak.
ונראה דברשעים המדה להיפוך והטעם ע"פ מאמרם ז"ל בבני ישראל הקב"ה מצרף מחשבה טובה למעשה. וברשעים מצרפין מחשבה רעה למעשה.
It seems that for the wicked the measure is reversed, and the reason is according to the teaching: for Israel, God joins a good thought to the deed, while for the wicked a bad thought is joined to the deed.
Thus divine accounting amplifies good intention for the righteous and bad intention for the wicked.
וכל עובדא טובה או רעה נראה שנמצא מזה שורש באבות. רק שיצא עתה בזרעם לפועל אבל בכח נמצא הכל בהאבות.
Every good or bad act appears to have its root in the ancestors; it now emerges in the descendants in actuality, but potentially it existed already in the ancestors.
Deeds of children reveal latent spiritual tendencies inherited from earlier generations.
ולכן כשזוכה הצדיק לשמחה יש בזכות זה חלק במחשבה באבותיו ומצרפו הקב"ה למעשה. וניתן להאבות חלק בהשמחה.
Therefore, when a righteous person merits joy, there is in this merit a share attributed to the thoughts of his ancestors, and God joins it to the deed, giving the ancestors a share in the joy.
Righteous joy activates ancestral merit, allowing ancestors to partake in the realized blessing.
משא"כ בעונש אין המחשבה נחשב. וברשעים להיפוך כנ"ל.
But in punishment the thought is not counted; and for the wicked it is the opposite, as above.
Affliction does not retroactively implicate righteous ancestors, but wicked ancestors are linked to the negative deeds of their descendants.
Summary: The Sefat Emet explains that divine reciprocity differs for the righteous and the wicked. Joy of Israel extends upward to gladden righteous ancestors, while their suffering is not shown to them. For the wicked, suffering of descendants is revealed to their ancestors because evil intentions are combined with deeds, and roots of wrongdoing lie in earlier generations.
