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.But if her husband altogether hold his peace at her from day today,.... Said not one word to her day after day, neither on the day he heard her vow, nor the day following:

then he establisheth all her vows, or all her bonds, which are upon her; by his silence:

he confirmeth them, because he held his peace at her, in the day that he heard them; for not to contradict them was to confirm them.
