(Mishnah): If one was Madir (forbade through a vow) his wife from benefit from him, up to 30 days, he gets someone to finance her. Beyond this, he divorces her and pays a Kesuvah.

R. Yehudah says, a Yisrael, for one month he may keep his wife, but for two months he divorces her and pay her Kesuvah;

A Kohen's wife (he cannot remarry her if he divorces her) - for two months he keeps her. For three, he divorces her and pays a Kesuvah.

(Gemara) Question: A Mishnah there teaches one who was Madir his wife from Bi'ah [Beis Shamai say, up to two weeks he may stay married. Beis Hillel say, up to one week. Beyond this, he divorces her and pay her Kesuvah], and here you say so (he can forbid her to benefit from him for up to 30 days, and need not divorce her)?!

Answer: There, he was Madir her from his body (this is more painful for her). Here, he was Madir her from his property.

Question: Can one vow not to pay his debt?! (He is obligated to feed her!)

Answer #1 (R. Yosi ben Chaninah): Since he is destined to divorce her and pay a Kesuvah to her and diminish her food, it is as if he has no obligation. (Since he can uproot her rights to food at any time, this shows that each day is a new Chiyuv. His vow preceded the Chiyuv.)

Question: She should sit and wait - if he divorces her, fine. If not, he feeds her (this shows that from the beginning he was obligated! Why does his vow take effect?)

Answer #2: This is like the opinion that feeding one's wife is not a Torah obligation. (Rather, Chachamim enacted that she work for him, and feeding her is like paying a debt owed due to her labor);

(Beraisa): Beis Din does not apportion food for a woman [whose husband is away] from Demei Shevi'is (money paid for Peros Shemitah, for it is like paying a debt from Shemitah), but she is fed [when she is] by her husband in Shevi'is. (He owes to her the Peros themselves. This is unlike paying a debt from Peros Shemitah.)

Question: They should make her like a worker [whose labor is] not worth a Perutah! (Feeding her is unlike paying a debt. Rather, they enacted that she work for him, and that he feed her, but not as payment. Rather, it is like a worker who is entitled to eat, even if his labor is not Shaveh Perutah, and there is no debt!)

Answer: This shows that they did not make her like a worker not worth a Perutah. (Feeding her is like paying a debt due to her labor. We explained this like RIDVAZ.)

Question: He should set up a Parnes (someone to feed her, and her husband will pay him! Why must he divorce her if he vowed for more than a month?)

This is like [a Mishnah] teaches. Ploni is Mudar Hana'ah (may not benefit from) me (and he does not have what to eat), and I do not know what I will do [to help him]. He sets up a Parnes.

Answer: A woman has the right to say 'I do not want to be financed through someone else, rather, through my husband.'

Question (Mishnah): One who feeds his wife through a third party...

Answer: Here (that Mishnah) is when she accepted [to be fed through a third party]. Here (our Mishnah) is when she did not accept.

Question: If she did not accept, even for one day he should not set up [a Parnes. He divorces her and pays a Kesuvah!]

Answer: She puts up with him for 30 days - perhaps he will find a Pesach for his vow (a reason to consider it a mistake, and a Chacham will permit it).

(Shmuel): [Our Mishnah] discusses one who vowed for 30 days, but if he vowed forever, immediately he divorces her and pays a Kesuvah.

(R. Ze'ira citing R. Avina citing Rav): Even if he vowed forever, she puts up with him for 30 days. Perhaps he will find a Pesach for his vow.

Some teach 30 days, and some teach until 30 days;

The one who teaches 30, he supports Rav (the vow was forever; she puts up with him for 30 days). The one who teaches until 30 days, he supports Shmuel (the vow was up to 30 days, therefore she puts up with him).
