'Vows' in the Bible

“This is the ritual of the Nazirite who vows his offering to the Lord for his consecration, in addition to whatever else he can afford; he must fulfill whatever vow he makes in keeping with the ritual for his consecration.”

These things ye shall do unto the LORD in your set feasts, beside your vows, and your freewill offerings, for your burnt offerings, and for your meat offerings, and for your drink offerings, and for your peace offerings.

If a man makes a vow to the Lord or swears an oath to bind himself with a pledge [of abstinence], he shall not break (violate, profane) his word; he shall do according to all that proceeds out of his mouth.

“Also if a woman makes a vow to the Lord and binds herself by a pledge [of abstinence], while living in her father’s house in her youth,

And her father hear her vow, and her bond wherewith she hath bound her soul, and her father shall hold his peace at her: then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand.

But if her father disallow her in the day that he heareth; not any of her vows, or of her bonds wherewith she hath bound her soul, shall stand: and the LORD shall forgive her, because her father disallowed her.

“If a woman marries while her vows or the rash commitment she herself made are binding,

And her husband heard it, and held his peace at her in the day that he heard it: then her vows shall stand, and her bonds wherewith she bound her soul shall stand.

But if, on the same day her husband hears and disallows her, then he has revoked her vows that she made for herself, along with any hasty vows that she spoke and to which she pledged herself to fulfill. The LORD will forgive her."

And her husband heard it, and held his peace at her, and disallowed her not: then all her vows shall stand, and every bond wherewith she bound her soul shall stand.

But if her husband hath utterly made them void on the day he heard them; then whatsoever proceeded out of her lips concerning her vows, or concerning the bond of her soul, shall not stand: her husband hath made them void; and the LORD shall forgive her.

But if her husband altogether hold his peace at her from day to day; then he establisheth all her vows, or all her bonds, which are upon her: he confirmeth them, because he held his peace at her in the day that he heard them.
