But every vow of a widow, and of her that is divorced, wherewith they have bound their souls, shall stand {f} against her.

(f) For they are not under the authority of the man.

Wesley's Notes

30:9 Widow or divorced - Though she be in her father's house, whither such persons often returned.

Jamieson-Fausset-Brown Bible Commentary

9. every vow of a widow-In the case of a married woman, who, in the event of a separation from her husband, or of his death, returned, as was not uncommon, to her father's house, a doubt might have been entertained whether she was not, as before, subject to paternal jurisdiction and obliged to act with the paternal consent. The law ordained that the vow was binding if it had been made in her husband's lifetime, and he, on being made aware of it, had not interposed his veto [Nu 30:10, 11]; as, for instance, she might have vowed, when not a widow, that she would assign a portion of her income to pious and charitable uses, of which she might repent when actually a widow; but by this statute she was required to fulfil the obligation, provided her circumstances enabled her to redeem the pledge. The rules laid down must have been exceedingly useful for the prevention or cancelling of rash vows, as well as for giving a proper sanction to such as were legitimate in their nature, and made in a devout, reflecting spirit.

Matthew Henry's Concise Commentary

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.
