What does Numbers 30:4 mean?

and her father heareth her vow, and her bond wherewith she hath bound her soul, and her father holdeth his peace at her; then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand.

And her father hear her vow, and her bond wherewith she hath bound her soul, and her father shall hold his peace at her: then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand.

and her father heareth her vow, and her bond wherewith she hath bound her soul, and her father holdeth his peace at her; then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand.

If her father, hearing of her oath or the undertaking she has given, says nothing to her, then all her oaths and every undertaking she has given will have force.

and her father hath heard her vow, and her bond which she hath bound on her soul, and her father hath kept silent at her, then have all her vows been established, and every bond which she hath bound on her soul is established.

If a woman vow any thing, and bind herself by an oath, being in her father's house, and but yet a girl in age: if her father knew the vow that she hath promised, and the oath wherewith she hath bound her soul, and held his peace, she shall be bound by the vow:

and her father hear her vow, and her bond wherewith she hath bound her soul, and her father shall be silent at her, then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand.
