In today's study of the Talmud Bavli, specifically Daf Mem Zayin, we dedicate our learning to the elevation of the souls of Avraham ben Esther and Alte Feiga bas Nechamah, as well as for a complete recovery for Mikki ben Jamie, and all those who are ill among the people of Israel. May it be the will of Hashem that they find peace in Gan Eden.
We commence our examination on Mem Zayin amud rishon, beginning with a question posed by Resh Lakish. He inquires about a situation where a person bows down to a palm tree, specifically asking if one may use the palm frond, or lulav, for the mitzvah of the holiday. The Gemara elaborates on this, presenting a case where the tree was planted with the intention of idolatry. In such a scenario, it is universally accepted that the tree is forbidden even for personal use, let alone for a mitzvah.
However, the discussion shifts to trees that were planted without such intentions but were later worshipped. Here, we see a division of opinions, particularly between Rabbi Yossi and the Rabbanan. According to Rabbi Yossi, even if the tree was initially permissible, once it has been worshipped, it becomes forbidden for personal use, and certainly for a mitzvah. The Gemara then contemplates whether the lulav can be used for a mitzvah if the tree was not originally intended for idolatry but was later worshipped.
Continuing, the Gemara introduces a new element via Rav Dimi, who raises a question regarding a tree that was an asherah but was nullified. The crux of the issue lies in whether something that has been pushed away can be reinstated for use in a mitzvah. This leads to a broader discussion about whether a mitzvah can be reinstated once it has been set aside.
To illustrate this, the Gemara references the mitzvah of covering blood after slaughtering an animal. If the blood was covered by wind and then uncovered, one is required to cover it again. This suggests that a mitzvah that has been pushed away can indeed be reinstated. The implications of this discussion are significant for our original question regarding the lulav.
As the conversation progresses, Rav Papa introduces a further inquiry regarding the implications of bowing down to an animal and the potential use of its wool for tcheiles. The Gemara examines whether the wool from an animal that was worshipped can be used for mitzvah purposes, particularly in the context of priestly garments. This leads to a deeper exploration of the status of items used for mitzvah versus those used for idolatry.
The Gemara then addresses the case of someone who bows to a wellspring, questioning whether the water from the wellspring can be used for nisuch hamayim during Sukkot. The discussion revolves around whether the act of bowing to the water makes it forbidden for ritual use. Ultimately, the Gemara concludes that if the water is flowing and continuously renewed, it may still be permissible.
We also encounter a Mishnah discussing the implications of building a wall adjacent to idolatrous practices. If a wall falls down, the individual may not rebuild it in a way that benefits the idolatrous practice. Instead, they must move inwards to create a new wall, thus ensuring they do not inadvertently support idolatry.
In another Mishnah, we learn about three types of houses that are forbidden due to their association with idolatry. The first is a house built for the purpose of idolatry, which remains forever forbidden. The second is a house that was initially built for residence but later adorned for idolatrous purposes; in this case, one can remove the idolatrous elements to permit the house. The third type involves a house that temporarily housed an idol; once the idol is removed, the house is permissible.
Through these discussions, the Gemara emphasizes the importance of intention and the specific circumstances surrounding each case. The distinctions between different situations highlight the nuanced approach of Jewish law regarding idolatry and mitzvot. The conclusion of the study leaves us with profound insights into the nature of holiness, the potential for reinstatement of mitzvah, and the ongoing relevance of these teachings in our lives today.
