'Vow' in the Bible

“Speak to the Israelites and tell them: When a man or woman makes a special vow, a Nazirite vow, to consecrate himself to the Lord,

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

“You must not cut his hair throughout the time of his vow of consecration. He must be holy until the time is completed during which he consecrates himself to the Lord; he is to let the hair of his head grow long.

“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.”

and you make a fire offering to the Lord from the herd or flock—either a burnt offering or a sacrifice, to fulfill a vow, or as a freewill offering, or at your appointed festivals—to produce a pleasing aroma for the Lord,

“If you prepare a young bull as a burnt offering or as a sacrifice, to fulfill a vow, or as a fellowship offering to the Lord,

Then Israel made a vow to the Lord, “If You will deliver this people into our hands, we will completely 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.”

When a man makes a vow to the Lord or swears an oath to put himself under an obligation, he must not break his word; he must do whatever he has promised.

“When a woman in her father’s house during her youth makes a vow to the Lord or puts herself under an obligation,

and her father hears about her vow or the obligation she put herself under, and he says nothing to her, all her vows and every obligation she put herself under are binding.

But if her husband prohibits her when he hears about it, he will cancel her vow that is binding or the rash commitment she herself made, and the Lord will forgive her.

“Every vow a widow or divorced woman puts herself under is binding on her.

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

Her husband may confirm or cancel any vow or any sworn obligation to deny herself.
