THE ORDER OF THE MISHNAH
Answer #2: Rather, the Tana is not particular. Sometimes he begins with the first matter, and sometimes with the last law.
Answer #3: Our Tana explains Yados first because they are expounded from a verse (so the law is dearer to him).
Question: If so, he should teach about Yados first!
Answer #1: He taught Kinuyim first, because they are mid'Oraisa (and are well known; they need not be expounded). He explains Yados first, because they are expounded.
Question: This is like the opinion that Kinuyim are the words Nochrim use for these matters. According to the opinion that Chachamim invented Kinuyim, how can we answer? (Even if this opinion agrees that Kinuyim are mid'Oraisa, they are not known more than Yados!)
Answer #2: The Mishnah did not explicitly teach Yados. We said that it is abbreviated. We can say that the full version teaches Yados first, as follows:
Every Yad for a Neder is like saying the full Neder. Every Kinuy for a Neder is like saying 'Neder'. The following are Yados - if one said... The following are Kinuyim: Konam, Konach...
THE SOURCE FOR YADOS
Question: From which verse do we derive Yados?
Answer #1: We learn from "Ish...Ki Yafli Lindor Neder Nazir Lehazir la'Shem";
(Beraisa): "Nazir Lehazir" teaches that Kinuyim and Yados work for Nezirus. (We do not learn Kinuyim from the verse. 'Kinuyim' was taught needlessly (Rosh), or should be deleted from the text (Ran).)
Question: This teaches about Nezirus. What is the source regarding Nedarim?
Answer: "Neder Nazir" equates Nedarim and Nezirus to each other:
Just like Yados work for Nezirus, also for Nedarim;
Just like one who transgresses a Neder or delays fulfilling a Neder (to bring a Korban) transgresses 'Bal Yachel' and 'Bal Te'acher', the same applies to Nezirus;
Just like a father or husband can annul the Nedarim of his daughter or wife, he can annul her Nezirus;
Question: We learned Yados Nezirus from "Nazir Lehazir." We should likewise learn Yados Nedarim from "Lindor Neder"! (Why must we learn from a Hekesh?)
Answer: Had it said "Neder Lindor", this would be correct. "Lindor Neder" is grammatically normal. The Torah speaks as people do; we do not expound it.
Question: This is like the opinion that the Torah speaks as people do (and we need not expound it);
According to the opinion that disagrees (and expounds every extra word), what do we learn from "Lindor Neder"?
Answer (and Answer #2 to Question (a)): It teaches that Yados of Nedarim are like Nedarim;
The Hekesh teaches that Yados of Nezirus are like Nezirus;
He expounds "Nazir Lehazir" to teach that if a Nazir accepted Nezirus, it takes effect (he must fulfill another term of Nezirus after his current Nezirus).
Question: According to the other opinion, how do we know that one can accept a double Nezirus?
This is not difficult according to the opinion that Nezirus does not take effect on Nezirus.
According to the opinion that Nezirus takes effect on Nezirus, how can we answer?
Answer #1: The Torah wrote "Lehazir" instead of 'Lizor' to teach this.
Answer #2 (and Answer #3 to Question (a) - Chachamim of Eretz Yisrael): Some learn Yados from Lindor Neder, and some learn from "k'Chol ha'Yotzei mi'Piv Ya'aseh." (Ran - the latter verse also teaches that Nezirus takes effect on Nezirus.)
ISURIM LEARNED FROM NEDARIM TO NEZIRUS
Question: Granted, one can transgress (only) Bal Yachel of Nedarim if he vowed to eat a loaf and did not eat it;
How can one transgress (only) Bal Yachel of Nezirus?
If he eats (grapes), he (also) transgresses Bal Yochal (the Isur to eat). If he drinks wine, he (also) transgresses Bal Yishteh (the Isur to drink)!
Answer (Rava): He also transgresses Bal Yachel for Nezirus.
Question: How can Bal Te'acher apply to Nezirus?
Once he says 'I am a Nazir', (he is immediately a Nazir.) If he eats (grapes), he transgresses Bal Yochal. If he drinks wine, he transgresses Bal Yishteh!
Answer #1: The case is, he said "When I want, I will be a Nazir."
Objection: But in such a case, there is never Bal Te'acher!
Answer #2 (Rava): It applies when he said 'I will be a Nazir before I die.' He is (obligated to become) a Nazir immediately;
This is like a Kohen who gave a Get and said that it will take effect just before he dies. His wife is immediately forbidden to eat Terumah, lest he die right away;
Also here, he is (obligated to become) a Nazir immediately, lest he die right away!
