The Eddie B. Sit Edition, an audio series of the Talmud Bavli, specifically focusing on the Gemara Yevamot and Masechet Yevamot, has been dedicated and sponsored by our dear friend Mr. Isaac Jamal and his wife, in honor of his family and for their success and prosperity in all their endeavors. May he merit to raise his children in the ways of the Torah, may they bring him much nachat, and may he be blessed with health and happiness, favor and kindness in the eyes of both Hashem and humanity, and may he enjoy blessings in all aspects of life. Amen.
As we study Masechet Yevamot, it is noteworthy that many of the cases require diagrams. We have chosen the Sefer Tziyurim L'Masechet Yevamot for our diagrams, authored by Aaron Shlomo ben Rabbi Baruch Moshe Hafner, which is available in bookstores. Therefore, when we refer to pages, we are referencing this sefer.
Today's daf is being studied for the elevation of the soul of Avraham ben Esther, and may the Ruach Hashem rest upon him in Gan Eden. Amen. We begin today's daf on He amud rishon, right at the top line. Let us quickly review where we left off. The Gemara was attempting to find a source for the principle of aseh doche lo ta'aseh, which means that a positive commandment overrides a negative commandment.
The Gemara concluded that according to Rabbi Ishmael, as taught in Tana d'vei Rabbi Ishmael, this principle is derived from the juxtaposition of the commandment of tzitzit and the prohibition of shatnez. The verse states: "You shall not wear shatnez, wool and linen together; you shall make for yourself fringes." From this juxtaposition, we learn that while one is prohibited from wearing shatnez, one is allowed to wear tzitzit made from such a mixture. Therefore, the positive commandment of tzitzit overrides the prohibition of shatnez.
The Gemara explains that the only time one can learn from juxtaposition is when there is an extra word allowing for the derasha of smuchin. According to Rabbi Ishmael, the extra words are "wool and linen" because he holds that whenever the Torah mentions the word beged, it automatically refers to tzemer and pishtim, as learned from negaim. Thus, the verse states, "A garment of shatnez shall not come upon you." Since it already states beged, the additional mention of tzemer and pishtim is considered extra, allowing for the derasha of smuchin.
The Gemara then states that this interpretation is valid according to Tana d'vei Rabbi Ishmael. However, it poses a question regarding the Rabbanan, who do not accept this derasha. They do not consider stam beged to automatically imply tzemer and pishtim, thus requiring the explicit mention of tzemer and pishtim in the verse. Therefore, they lack the smuchin needed to establish the principle of aseh doche lo ta'aseh.
The Gemara suggests that the Rabbanan derive this principle from another source, specifically from the laws of tzaraat. At the end of the purification process for a metzora, who has been afflicted with leprosy, the Torah instructs that he must shave all the hair on his body. The verse states: "And on the seventh day, he shall shave all his hair, his head and his beard." The Gemara questions why the verse needs to mention "his head" after stating "all his hair." The braita explains that this additional mention is necessary because of another verse that states, "You shall not round off the corners of your head," which prohibits cutting the pe'ot of one's hair.
Thus, when it states that he must shave his head, it seems contradictory to the prohibition against cutting the pe'ot. The Gemara resolves this by saying that the verse teaches that a metzora is indeed included in the prohibition against cutting the pe'ot. However, the positive commandment to shave his head overrides this prohibition. Consequently, we see that a positive commandment can override a negative commandment, as the shaving of the metzora is a positive commandment.
The Gemara continues to analyze the implications of this principle. It notes that there is a debate among the sages regarding what constitutes an infraction of the prohibition against cutting the pe'ot. Some hold that cutting the pe'ot refers specifically to trimming the sideburns while leaving the rest of the hair, while others argue that shaving the entire head bald would also constitute a violation. Thus, we establish that the positive commandment of shaving the head, which is a requirement for the metzora, overrides the prohibition against cutting the pe'ot.
At this juncture, the Gemara acknowledges that this ruling provides a clear example of aseh doche lo ta'aseh. However, it challenges the notion that this principle applies uniformly across all cases. The Gemara argues that the prohibition of cutting the pe'ot is not a strong prohibition since it does not apply to women, suggesting that it is a weaker form of a negative commandment. Therefore, the Gemara asks whether this principle can be applied to a more stringent negative commandment.
To address this, the Gemara proposes examining the shaving process of the metzora in relation to the requirement of shaving his beard. The verse states that he must also shave his beard, and the Gemara questions why this is necessary when it has already stated that he must shave all his hair. The braita again poses the question of why the verse emphasizes the beard. The Gemara explains that this is due to another prohibition that states one must not shave the corners of the beard, indicating that even though the metzora is allowed to shave, he is still restricted in how he does so.
Continuing this line of reasoning, the Gemara seeks to clarify whether the principle of aseh doche lo ta'aseh can be applied when there is a prohibition involving karet. The Gemara presents a series of proofs and counterarguments, examining cases such as milah and Pesach. It concludes that while these cases demonstrate the power of a positive commandment to override a negative commandment, they also present unique stringencies that complicate their application to general principles.
Ultimately, the Gemara asserts that the principle of aseh doche lo ta'aseh does not apply uniformly when the negative commandment carries the consequence of karet. It necessitates a specific verse to clarify that in cases of ervah, such as achot ishto, the positive commandment of yibbum does not override the prohibition. The Gemara concludes by emphasizing the importance of these distinctions in halachic rulings and the necessity of scriptural support to navigate complex legal scenarios.
In summary, the study of Masechet Yevamot reveals profound insights into the interplay of positive and negative commandments, illustrating how the Torah provides guidance through its intricate laws and teachings. Each ruling is carefully considered, ensuring that the principles of aseh and lo ta'aseh are applied with precision and respect for their halachic significance.
