The husband is the head of the wife as Christ is the head of the church. He is the savior of the body. Ephesians 5:23 (Christ is the savior of our souls)
When a man makes a vow to Jehovah, or swears an oath putting himself under an obligation, he must not break his word. He must do whatever he promised.
A woman’s covering while in her father’s house
When a unmarried woman - in her father’s house ... makes a vow to Jehovah, or puts herself under an obligation, and her father hears her vow and ... holds his peace: Then all of her vows shall stand and every obligation that she has put herself under shall stand.
But if her father disallows her in the day that he hears of it, not any of her vows, or of her oaths that she obligated herself with shall stand and Jehovah will forgive her, because her father disallowed her.
Her covering if she has a husband
If she has a husband when she vows or swears with her lips and obligates herself; and her husband hears it and holds his peace in the day that he hears it, her vows shall stand and every obligation that she has put herself under shall stand.
But if her husband disallows her on the day that he hears it; then he shall make her vow which she vowed and that which she swore with her lips of none effect and Jehovah shall forgive her.
Every vow and every binding oath to obligate her soul her husband may establish, or her husband may make void.
But if her husband altogether holds his peace at her from day to day; then he establishes all of her vows and all of her obligations: He confirms them because he held his peace in the day that he heard them.
If he shall any ways make them void after he has heard them; then he shall bear her iniquity.
These are the statutes which Jehovah commanded Moses between a man and his wife and between the father and his daughter, being a youth in her father's house. Numbers 30:2-8 & 13-16
Rebellion is like the sin of witchcraft and defiance is like wickedness and idolatry. 1 Samuel 15:23a
