Numbers 30:13

“Every vow, and every binding oath to afflict the soul, etc.] By fasting, as Aben Ezra observes; as when a vow was made, or a person bound herself by an oath to abstain from such and such food, or to fast on such a day; to keep a fast which was not appointed, to set apart a day for fasting, besides the grand and general fast on the day of atonement: Jarchi from hence gathers, that a man only makes vows of afflicting the soul, or vows of fasting; but this is not said by way of limitation and restriction, but by way of amplification and illustration, giving a particular instance, by which others may be judged of: her husband may establish it, or her husband may make it void, just as he pleased;…”

“To afflict her soul - Herself by fasting, by watching, or the like. And these words are added to shew that the husband had this power not only in those vows which concerned himself or his estate, but also in those which might seem only to concern her own person, or body, and the reason is, because the wife's person or body being the husband's right; she might not do any thing to the injury of her body without his consent. Numbers 30:15”
