Nedarim

We learnt: [If one says to his wife, 'Konam be] that which you benefit from me until the Festival, if you go to your father's house before Passover': if she goes before Passover, she may not benefit from him until the Festival, but is permitted to go after Passover. [Thus,] if she goes, she is forbidden, but not otherwise?  — Raba answered: The same law applies that even without going she is forbidden. But if she goes, she is forbidden [to benefit], and receives lashes [if she does]; if she does not go, she is merely forbidden. An objection is raised: [If he says,] 'This loaf [of bread be forbidden] to me to-day, if I go to such and such a place to-morrow: if he eats it, he is liable to an injunction, 'he shall not go'!  — Does he [the Tanna] teach: he may eat it — [surely] he teaches, 'if he eats it' so that if he eats it he is under the injunction not to go.  [The Baraitha continues:] If he goes, he violates the injunction, he shall not break his word.  But there is no [clause] teaching that he goes [on the second day]: this contradicts Rab Judah!  — R. Judah answers you: In truth, he could teach, he goes: but since the first clause teaches, 'if he eats', not being able to teach.'he eats'.  the second clause too teaches, 'if he goes IF ONE SAYS TO HIS WIFE, KONAM IF I COHABIT WITH YOU.' HE IS LIABLE TO [THE INJUNCTION,] HE SHALL NOT BREAK HIS WORD. But he is obligated to her by Biblical law, as it is written, her food, her raiment, and her marriage rights he shall not diminish?  — It means that he vows, 'The pleasure of cohabitation with you be forbidden me': thus he surely denies himself the enjoyment of cohabitation.  For R. Kahana said: [If a woman says to her husband,] 'Cohabitation with me be forbidden to you,' she is compelled to grant it, since she is under an obligation to him. [But if she says,] 'The pleasure of cohabitation with you be forbidden me,' he is forbidden [to cohabit]. Since one may not be fed with what is prohibited to him. MISHNAH. [IF HE SAYS,] '[I SWEAR] AN OATH NOT TO SLEEP, OR, 'TALK,' OR, 'WALK,' HE IS FORBIDDEN [TO DO SO]. [IF HE SAYS,] 'A KORBAN BE WHAT I MIGHT NOT EAT OF YOURS,'  [OR] 'OH KORBAN! IF I EAT OF YOURS,' [OR] 'WHAT I MIGHT NOT EAT OF YOURS BE NOT A KORBAN UNTO ME,' HE IS PERMITTED [TO EAT OF HIS NEIGHBOURS'].
