The Edat Bais-It edition of the audio series on Talmud Bavli, specifically Masechet Nazir, has been dedicated by our esteemed friends Chaimy and Dina Dana. May God protect and sustain them, granting success to all their children, that they should be educated according to our holy Torah, and grow up to merit Torah, commandments, marriage, and good deeds, particularly a complete healing for Moshe ben Dina and Penina bat Esther. May God's healing be swift and may it be His will, and let us say, Amen. The study today is on Daf Nun Bet. We dedicate today’s learning for the elevation of the soul of my grandfather, Meir Yosef ben Sarah, and for Avraham ben Esther, and may God comfort them in the Garden of Eden, Amen.
We are currently engaged in the Gemara on Nun Bet Amud Bet, and we are a few lines from the bottom, beginning with the words of Rami bar Chama. In our last sugya, the Gemara left us with a question regarding tumah (ritual impurity) concerning the shidra and gulgoleth (spinal column and skull). The Mishnah stated that certain matters can bring tumah to a nazir (a person who has taken a vow of abstinence), to the extent that if he is in the same ohel (tent) with these bones, he would have to shave like a nazir tamei (impure nazir) and then start the process anew after bringing his korbanot (offerings).
The Gemara had a safek (doubt): does it mean the spinal column and skull collectively, or just one of them? The Gemara attempted to bring proofs in support of either position but was ultimately unsuccessful. We also noted that the majority of the frame of the body, referred to as rov binyan, includes bones such as the thigh and shin bones. Although these do not constitute the majority of bones, they represent the majority of the body's height and can also transmit tumah. Similarly, rov minyan refers to the 125 bones typically found in the hands and feet, which can also cause tumah.
The Mishnah also mentioned a law regarding rova hakav (a quarter of a kav) of bone fragments. If there is a measurement of rova hakav in a box, it can cause tum'at ohel, which means the nazir will become tamei. The Gemara inquired about the source of this rova hakav. It suggested that it may derive from either rov minyan or rov binyan, meaning either a small piece of the 125 bones or a piece from the majority of the frame that equals the measurement of rova hakav.
However, the Mishnah does not specify the law of rova hakav concerning the shidra and gulgoleth. It is essential to understand that there are two distinct laws here. If you have rov binyan, which means the majority of those bones, that suffices. Alternatively, if you have rov minyan, you still need to consider the rova hakav measurement. The Gemara seeks to clarify whether this rova hakav applies to the shidra and gulgoleth as well.
Now, Rami bar Chama posed the question: what is the law regarding rova atzamot from the shidra and gulgoleth? The Gemara noted that the Mishnah only discussed the law of rova hakav concerning rov binyan and rov minyan. The Gemara further elaborates that the shidra and gulgoleth are treated with special status, as they are significant parts of the body that can independently transmit tumah. Thus, the question arises whether the law of rova hakav applies to them as well.
The Gemara continues with the inquiry: if a collection of whole bones contaminates through ohel, does a quarter kav of fragments from those bones also transmit tumah through ohel? The Mishnah teaches a law concerning a nazir based on a halacha leMoshe miSinai (a law transmitted to Moses at Sinai). Although a quarter kav of bones derived from the majority of the skeleton transmits tumah via an ohel, a nazir who is contaminated does not fall under the laws of nazir tamei unless he contracts tumah from half a kav of these bones.
This distinction is crucial, as normally the measurement for tum'at ohel with these bones is a quarter of a kav. However, the special law for a nazir is that the measurement is a half a kav. The Gemara now questions whether this law applies solely to fragments derived from the majority of the skeleton or if it also applies to fragments from the shidra and gulgoleth as well.
Rami bar Chama asks: if you have a quarter kav of bones from the shidra and gulgoleth, what is the law? The Gemara suggests that the Mishnah refers to half a kav of bones derived from other parts of the body, but perhaps the shidra and gulgoleth are more stringent.
The Gemara continues to explore this issue, noting that if the shidra and gulgoleth are treated as significant parts of the body, then even a quarter kav of fragments from these areas may impart tumah. The discussion centers around whether the rova hakav applies to these specific bones, which are inherently more significant.
Overall, the Gemara seeks to clarify the nuances of tumah regarding the nazir and the implications of the Mishnah’s teachings on the laws governing tumah from different parts of the body, especially those that are considered more critical, such as the shidra and gulgoleth.
