Parallel
Numbers 30:9
Brenton's English Septuagint · Berean Standard Bible
But if her husband should straitly forbid [her] in the day in which he should hear her, none of her vows or obligations which she has contracted upon her soul shall stand, because her husband has disallowed her, and the Lord shall hold her guiltless.
Every vow a widow or divorced woman pledges to fulfill is binding on her.
