Solemn promises by women

³ When a woman makes a solemn promise to the Lord or a binding obligation while she is young and in her father’s household, ⁴ and her father hears her solemn promise or her binding obligation for herself and keeps silent^[a]—then all her solemn promises and any of her binding obligations for herself will stand.
