Numbers 30:10

In her husband's house, i.e. if she that now is a widow, or divorced, made that vow whilst her husband lived with her; as suppose she then vowed, that if she was a widow, she would give such a proportion of her estate to pious or charitable uses, of which vow she might repent when she came to be a widow, and might believe or pretend she was free from it, because that vow was made in her husband's lifetime, which is here granted, in case her husband then disallowed it, but denied, in case by silence or otherwise he consented to it. And thus this law is sufficiently distinguished from that above, Numbers 30:6.
