(Mishnah): Every Kinuy (substitute name) for Nedarim (vows, one who says them) is like [one who says] Nedarim, all Kinuyim of Cherem (making something somewhat or totally like Hekdesh) are like Cherem, all Kinuyim of Shevu'os are like Shevu'os, and all Kinuyim of Nezirus are like Nezirus.

If one said to his friend 'I am Mudar (forbidden by a vow) from you', 'I am separated from you', 'I am distanced from you', 'that I will eat Lecha (from you)', or 'that I will taste Lecha (from you)', he is forbidden [to benefit from him].

If one said 'I am Menudeh to you', R. Akiva was inclined to be stringent about this.

If one said "like the vows of Resha'im..." (and he vowed)", his vow of Nezirus, Korban or Shevu'ah takes effect (this will be explained);

If he said "like Nedarim of Kesherim" it has no effect.

If he said "like their Nedavos (Hekdesh of an animal in which one takes no responsibility to compensate if it will be lost, stolen or blemished)", his vow of Nezirus or a Korban takes effect.

Question: This is according to R. Akiva, who says that [doubled expressions] are inclusions;

According to R. Yishmael, who says that they are doubled expressions, and the Torah spoke in it its way, e.g. "Haloch Halachta [Ki] Nichsaf Nichsafta", "Gunav Gunavti" [so we do not expound them], what is the source?

Answer - Question: It says "Ish Ki Yidor Neder la'Shem Oh Hishava Shevu'ah Le'esor Isar Al Nafsho Lo Yachel Devaro" - why does it say "k'Chol ha'Yotzei mi'Piv Ya'aseh"?

Answer: This teaches that Kinuyim for Nedarim are like Nedarim, and Kinuyim for Shevu'ah are like a Shevu'ah.

Question: What is the source that Kinuyim for Charamim are like Charamim?

Answer: [We learn from a Gezeirah Shavah] "Neder-Neder." Just like Neder said here (regarding Nedarim), Kinuyei Nedarim are like Nedarim, and Kinuyei Shevu'ah are like a Shevu'ah, also Neder said there (regarding Cherem), Kinuyei Charamim are like Charamim.

Question: What is the source that Kinuyim for Nezirus are like Nezirus?

Answer: [We learn from a Gezeirah Shavah] "Neder-Neder." Just like Neder said here (regarding Nedarim), Kinuyei Nedarim are like Nedarim, and Kinuyei Shevu'ah are like a Shevu'ah, also Neder said there (regarding Nezirus), Kinuyei Nezirus are like Nezirus.

Question: What does R. Akiva learn from "k'Chol ha'Yotzei mi'Piv Ya'aseh"?

Answer: This teaches that a Neder that is partially Batel is totally Batel.

Question: Does R. Yishmael not hold like this?! (He used this to teach that Kinuyim for Nedarim and Shevu'os are like Nedarim and Shevu'os.)

Answer: He learns all of them from there. This teaches that Kinuyei Nedarim are like Nedarim, and Kinuyei Shevu'os are like Shevu'os, and this teaches that a Neder that is partially Batel is totally Batel (for it could have said 'Kol' [ha'Yotzei mi'Piv...], and rather, it says "k'Chol". RAN (3b) - he can learn both, for the verse connotes both of them.)

Question: What does R. Yishmael learn from "Neder Nazir Lehazir"?

Answer: This teaches that one can accept on himself Nezirus during his days of Nezirus. (Do not say that it is like a Shevu'ah, and a second Shevu'ah does not take effect on a Shevu'ah.)

Question: Does R. Akiva not hold like this?! (He used this to teach that Kinuyei Nezirus are like Nezirus.)

Answer: He learns all (both) of them from there (for it could have said 'Lizor', and rather, it says "Lehazir"). This teaches that [Kinuyei Nezirus are like Nezirus, and] one can accept on himself Nezirus during his days of Nezirus.
