'Vow' in the Bible

Speak unto the children of Israel, and say unto them, When either man or woman shall separate themselves to vow a vow of a Nazarite, to separate themselves unto the LORD:

He is not to eat anything produced by the grapevine, from seeds to skin, during his vow.

All the days of the vow of his separation there shall no rasor come upon his head: until the days be fulfilled, in the which he separateth himself unto the LORD, he shall be holy, and shall let the locks of the hair of his head grow.

He will rededicate to Yahweh the days of his separation and bring a ram-lamb {in its first year} as a guilt offering. The former days [of his vow] will fall away because his separation was defiled.

This is the law of the Nazarite who hath vowed, and of his offering unto the LORD for his separation, beside that that his hand shall get: according to the vow which he vowed, so he must do after the law of his separation.

And will make an offering by fire unto the LORD, a burnt offering, or a sacrifice in performing a vow, or in a freewill offering, or in your solemn feasts, to make a sweet savour unto the LORD, of the herd, or of the flock:

And when thou preparest a bullock for a burnt offering, or for a sacrifice in performing a vow, or peace offerings unto the LORD:

And Israel vowed a vow unto the LORD, and said, If thou wilt indeed deliver this people into my hand, then I will utterly destroy their cities.

“You must offer these to the Lord at your appointed times in addition to your vow and freewill offerings, whether burnt, grain, drink, or fellowship offerings.”

If a man vow a vow unto the LORD, or swear an oath to bind his soul with a bond; he shall not break his word, he shall do according to all that proceedeth out of his mouth.

If a woman also vow a vow unto the LORD, and bind herself by a bond, being 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 disapproves of her [making her vow] on the day that he hears about it, none of her vows or her pledges by which she has bound herself shall stand; and the Lord will forgive her because her father has disapproved of her [making the vow].

"If she has a husband and she makes a vow that is binding on herself, or if she makes a hasty vow with her mouth that she pledges herself to fulfill,

and her husband hears her vow, yet remains silent on the day that he hears it, then her vows are to stand and the obligation to which she had pledged herself is to stand.

But if her husband disallowed her on the day that he heard it; then he shall make her vow which she vowed, and that which she uttered with her lips, wherewith she bound her soul, of none effect: and the LORD shall forgive her.

But every vow of a widow, and of her that is divorced, wherewith they have bound their souls, shall stand against her.

“If a woman in her husband’s house has made a vow or put herself under an obligation with an oath,

Every vow, and every binding oath to afflict the soul, her husband may establish it, or her husband may make it void.
