And if she vowed in her husband's house,.... Before his death, in his lifetime, or before divorced: the Targum of Jonathan adds, by way of explanation, "and not at age for marriage", understanding it of a betrothed, and not a married person; but Jarchi says, the Scripture speaks of a married one, which seems most likely:

or bound her soul by a bond with an oath; to fulfil her vow, to abstain from this, or to do that or the other thing.

And if she vowed in her husband's {h} house, or bound her soul by a bond with an oath;

(h) Her husband being alive.

30:10 If she vowed - If she that now a widow, or divorced, made that vow while 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 repented she was free from it, because that vow was made in her husband's lifetime; this is granted, in case her husband then disallowed it; but denied, in case by silence, or otherwise he consented to it.

30:3-16 Two cases of vows are determined. The case of a daughter in her father's house. When her vow comes to his knowledge, it is in his power either to confirm it or do it away. The law is plain in the case of a wife. If her husband allows her vow, though only by silence, it stands. If he disallows it, her obligation to her husband takes place of it; for to him she ought to be in subjection, as unto the Lord. The Divine law consults the good order of families. It is fit that every man should bear rule in his own house, and have his wife and children in subjection; rather than that this great rule should be broken, or any encouragement be given to inferior relations to break those bonds asunder, God releases the obligation even of a solemn vow. So much does religion secure the welfare of all societies; and in it the families of the earth have a blessing.
