I Did Not Come To Violate or Void the Laws

But To Fulfill Them.
(said Jesus.)

There are 613 basic ones, 10 core ones. The "Sum of all the laws and the prophets" are Love the Lord your God with all your heart, mind, soul, and strength and your neighbor as yourself.
There are laws against breaking vows. You cannot do it. It is against the laws.
There are at least 4 laws concerning making vows of marriage as they pertain to Kohein (Cohen) Priests. They could not marry a "harlot" a widow, a divorced or "profaned" person, meaning they had to marry virgins. There are no such requirement restrictions in the 613 for the Levitical priests who had other priestly duties and partook of the tithes concerning whom they could marry. There is NO LAW prohibiting marriage for either Kohein or Levitical priests as they were expected to marry. There is a blanket prohibition against any "Eunich" marrying a Daughter of Zion. Because Daughters of Zion deserve better than eunichs and are supposed to fulfill the requirement to "be fruitful and multiply."

You figure it out. "I did not come to Violate or Void the Laws, but to fulfill them."
