THE SOURCE THAT THEY ANNUL TOGETHER
(Beraisa - Tana d'Vei R. Yishmael): "Between a man and his wife, between a father and his daughter" teaches that both must annul the vow of a Na'arah Me'orasah.
Question: What does he learn from "If she will be to a man"?
Answer: He learns Rava's other law (70a. If an Arusah was widowed, her father can annul her vows until she remarries, just like he could annul her vows before her first Kidushin.)
Question: (Rava learned joint annulment from "If she will be to a man.") What does Rava learn from Tana d'Vei R. Yishmael's verse ("Between a man and his wife, between a father and his daughter")?
Answer: It teaches that a husband annuls vows that affect their relationship.
IF ONLY THE ARUS OR FATHER ANNULLED
Question: When an Arus annuls alone, does he cut half the vow (but the remainder is a full-strength vow)? Or, does he weaken the vow?
If she vowed from two olives, and her husband annulled the vow, and she ate the olives:
If he cuts the vow (and does not weaken it), she is lashed;
If he weakens it, she is not lashed.
Answer (Beraisa) Question: When do we say that that if the Arus dies, the father gets back authority to annul? (The answer to Question (a) is from the Seifa of this long Beraisa, on 69a.)
Answer: It is when the Arus died without hearing the vow, or after he annulled it, or if he died on the day he heard it, before he acted on it;
If the Arus affirmed the vow, or was silent on the day he heard it and died on a later day, the father cannot annul it.
If the father heard her vow and annulled it and died before the Arus heard it, authority to annul does not pass to the Arus.
If the Arus heard her vow and annulled it and died before the father heard it, authority to annul returns to the father.
If the Arus heard her vow and annulled it and the father died before hearing it, the Arus cannot annul it, since he can annul only in partnership.
