Shalom Aleichem. We continue in Chapter Reish Chaf Hei, 225. The discussion here centers on Bedikas Chametz—specifically, whether it should be done solely by the head of the household or with the participation of family members.
In the Alter Rebbe’s Shulchan Aruch, it is explained that the obligation of Bedikas Chametz rests on the head of the household, since it is his chametz. Ideally, because of the principle of “mitzvah bo yoser mibishlucho,” it is preferable that he perform the mitzvah himself rather than appointing others. Only if it is too difficult for one person to search the entire home should he involve family members.
However, in the Siddur, the Alter Rebbe presents it differently. There he writes that one should position the members of his household near him at the time of the bracha and have them participate in the search, without explicitly stating that this applies only when necessary. This seems to suggest that involving family members may be the preferred approach even initially.
The Rebbe addresses this apparent contradiction. First, he suggests that there may not be any real difference. The Siddur may simply be summarizing the Shulchan Aruch and assuming a typical case where one person cannot manage the entire search alone.
Even if we assume that the Siddur is advocating involving family members from the outset, the Rebbe rejects the explanation that this is due to concern that one person might become tired and not search properly. Such a concern is not established in halacha regarding men, and it would depend on the size of the home, which the Alter Rebbe does not specify.
Instead, the Rebbe offers a different understanding. Even though the obligation rests on the head of the household, there is value in including others in the performance of a mitzvah. Since he is already fulfilling the mitzvah, it is proper to allow family members to participate as well. They stand by the bracha, answer Amen, and take part in the search, thereby sharing in the mitzvah.
Additionally, once the head of the household has begun the mitzvah and performed part of it himself, he has fulfilled the aspect of “mitzvah bo.” At that point, there is no issue with having others assist and complete the task.
Practically speaking, in most homes today, especially where there are families, the size of the home makes it difficult for one person to conduct the entire search alone. Therefore, it is both practical and proper to involve family members, giving each person a role in the mitzvah.
Summary
While Bedikas Chametz is the responsibility of the head of the household, the Rebbe explains that it is proper to involve family members. This allows others to share in the mitzvah, and in practice, it is often necessary due to the size of modern homes.
