More on the husband/father revoking vows - with a parallel to the vow of becoming a nazir. Declaring oneself a Nazir bring a vow, of course. The point comes, though, when the man cannot revoke it - once he's confirmed it, it's upheld - or so it seems at first blush. Also, a new mishnah, which introduces new parameters for the difference between the father and the husband - specifically (again), if the father dies. Plus, the sources for this authority, and the complications of the shifts in the woman's status. Plus, the waiting period between betrothal and marriage, and the implications of it.
