Numbers 30:4

Her father; under which title seem to be comprehended, as in other places of Scripture, masters, magistrates, and all other superiors, in such cases wherein their right is given away by the inferior's vow; as for instance, when a servant vows to go a long journey for his friend, and his master will not permit him to do so; but not in other cases; as if a servant vows to do something for another in that time which his master alloweth to his own use and disposal, in this case his vow binds him, but not in the former. And her father shall hold his peace; his silence being an interpretative consent, and much more if he declares his approbation of it. Shall stand, i.e. be established, or confirmed, or be in force.
