Numbers 30:13

“Any vow or sworn obligation that would bring affliction to her, ¹  her husband can confirm or nullify. ² 

Her husband may confirm or nullify any vow she makes or any sworn pledge to deny herself.

"Every vow and every binding oath to humble herself, her husband may confirm it or her husband may annul it.

So her husband may either confirm or nullify any vows or pledges she makes to deny herself.

Any vow and pledge that she makes that may be to her detriment can be either affirmed or annulled by her husband.

Every oath, and every undertaking which she gives, to keep herself from pleasure, may be supported or broken by her husband.

Any vow or any binding oath to deny herself, her husband may allow to stand, or her husband may nullify.

"Every vow and every binding oath to afflict her soul, her husband may confirm it, or her husband may make it void.

“Any vow or sworn obligation that would bring affliction to her, ¹  her husband can confirm or nullify. ² 

¹ tn The sentence uses the infinitive construct לְעַנֹּת (lÿ’annot, “to afflict”), which is the same word used in the instructions for the day of atonement in which people are to afflict themselves (their souls). The case here may be that the woman would take a religious vow on such an occasion to humble herself, to mortify her flesh, to abstain from certain things, perhaps even sexual relations within marriage.

² tn Heb “or her husband can nullify.”
