It was the custom of scholars [that] as long as one's daughter had not left him, he would say to her: “All nedarim which you have made in my house are revoked.” And so, too, the husband —- before she would come under his authority —- would say to her: “All nedarim which you have made prior to coming under my authority are revoked,” for once she comes under his authority, he cannot revoke [them].
