b'The father and husband of a betrothed maiden may validate, or in partnership negate her vow \\u2022 If the father alone negated her vow, and the husband dies, according to Beis Hillel the vow is impaired, meaning the restriction is in force, yet there are no lashes for violation \\u2022 May one annul the validation or negation of a vow? \\u2022 What happens when validation and annulment are in conflict?'
