Explanation: [We know that elsewhere, Rubo k'Kulo.] since the Torah revealed about a Nazir "ba'Yom ha'Shevi'i Yegalchenu." This was not needed, for it already wrote v'Gilach!

Rather, this teaches that we require a full Tiglachas Mitzvah that does not leave over anything;

Inference: Here we require all. Elsewhere, the majority is like the full amount.

Assertion (Maharam): We discuss (infer about) elsewhere. However, regarding the corners of the beard, it says in Shabbos (94b) that one is liable for [the width of the end of] a scissors blade (two hairs), for "Pe'as" connotes a small amount.

Alternate text: The text in Seforim is 'the Torah says "Lo Yechalel."'

Rejection #1: This is wrong. This is not written regarding a warning about Tum'ah! (It is a Lav to marry women forbidden to Kehunah.)

Rejection #2: Below, it says explicitly that "Lehechalo" comes for this Drashah!

Explanation: Abaye comes to resolve the Mishnah and Beraisa;

Here (in the Beraisa), he is connected to the Mes and they warned him and pass another Mes to him. He is not liable, for he is already profaned;

Here (in our Mishnah), he is not connected. He already separated from the Mes, and they passed [another] Mes after he separated from the first, and they said to him "do not become Tamei";

He is not [considered to be] already profaned, and there is an increase of Tum'ah even on the same day, for while he is touching the Mes, one who touches him becomes Tamei for seven days;

This is like we expound in Avodah Zarah (37b) "Kol Asher Yiga Bo ha'Tamei Yitma" - one who touches one who touches [the Mes] is Tamei for seven days. After [the one touching the Mes] separated, one who touches him is Tamei until nightfall [after the day he immerses]. There is increased Tum'ah [while he touches]!

Explanation #1 (Ri): [Chiburei Adam b'Adam is] the third one, who touches one who touches one who touches the Mes. Surely, it is mid'Rabanan that he is Tamei for seven days;

We said that d'Yakriv bid'Yakriv is mid'Oraisa. This is only one who touches one who touches a Mes;

Citation (Avodah Zarah 37b): Yosef ben Yo'ezer testified that d'Yakriv bid'Yakriv is Tamei. [The Gemara asked] this is mid'Oraisa - "Kol Asher Yiga Bo ha'Tamei Yitma"!

We conclude that mid'Oraisa, b'Chiburim is Tamei seven days, and not b'Chiburei is Tum'as Erev. Chachamim decreed that even not b'Chiburim is Tamei seven days. Yosef ben Yo'ezer came and permitted.

Explanation #1: According to the Ri, mid'Oraisa b'Chiburim is one who touches one who touches a Mes. Not b'Chiburim is the third, who touches one who touches one who touches a Mes.

Explanation #2 (Rashi in Avodah Zarah): They decreed not b'Chiburim, even if he totally separated.
