Yehudah Ish Hutza hid himself in a cave for three days in order to understand this law that life essentials of this city have precedence over life essentials of another city;

He came to R. Yosi ben Chalafta, and told him 'I hid myself in a cave for three days in order to understand this law that life essentials of this city have precedence over life essentials of another city!'

[R. Yosi] called to his son R. Aba, and said to him 'what is the source that life essentials of this city have precedence over life essentials of another city?'

(R. Aba): "Tihyenah ha'Arim ha'Eleh [Ir Ir u'Migrasheha Sevivoseha]" - Tihyenah Ir (first this city will be), and afterwards u'Migrasheha Sevivoseha (the area around it).

R. Yosi (to Yehudah): What caused [that you did not know this]? It is because you [isolated yourself, and] did not learn with your colleagues!

Question: Granted, 'if I will bathe' (it is Inuy if she cannot bathe. Why can he annul) 'if I will not bathe'? She can bathe!

Answer (R. Mana): The case is, she said [before this] 'Konam, benefit from me is [forbidden] to you from when I will bathe, if I will bathe.'

Question: He can annul her [vow]!

Answer (R. Yosi bei R. Bun): The case is, she said 'Konam, benefit from my body is [forbidden] to you from when I will bathe.'

Question: He can force her [to have Bi'ah with him]! Did not Rav Huna say, [if she says] 'benefit from me is [forbidden] to you', he forces her to have Bi'ah with him. (She cannot uproot her obligation to him.) 'Benefit from you is [forbidden] to me', he annuls!

Answer: Here is different, for she forbade both his Hana'ah and her Hana'ah (MEICHAL HA'MAYIM).

(R. Aba Mari): [She vowed] 'if I will bathe [today] I will never bathe', or 'if I will adorn myself [today] I will never adorn myself.' (Rabanan holds that not bathing or adorning for one day is Inuy; R. Yosi disagrees.)

(Rabanan of Kisarin): [She vowed] 'if I will bathe [today] I will never adorn myself, and if I will adorn myself [today] I will never adorn myself.' (We explained this like PNEI MOSHE.)
