Leviticus 27:2 and if the vow was to separate his daughter from the company of men, and oblige her never to marry, such a power as this parents had not allowed them over their children, according to the laws of God or of men, in the Jewish nation; and therefore, be it which it will, what he had to do was to repent of this rash vow, and humble himself before God for making it, and not add sin to sin by performing it.
