We must keep our vows. Fathers and husbands have authority to overrule vows their family members make. Silence is consent, if they are aware of the vow.
How this is about Jesus
Interesting that bread and wine were given with every sacrifice. Jesus keeps these elements in the NT sacrament of the Eucharist, remembering His final sacrifice.
Jesus gives instruction for His house, the church, in the NT.
There is much family design instruction in chapter 30. It is a proof from Scripture that family leaders are to guide the spiritual practice of each member as shepherds.
