'Vow' in the Bible

"Speak to the children of Israel, and tell them: 'When either man or woman shall make a special vow, the vow of a Nazirite, to separate himself to Yahweh,

"'All the days of his vow of separation no razor shall come on his head, until the days are fulfilled, in which he separates himself to Yahweh. He shall be holy. He shall let the locks of the hair of his head grow long.

"'This is the law of the Nazirite who vows, and of his offering to Yahweh for his separation, besides that which he is able to get. According to his vow which he vows, so he must do after the law of his separation.'"

and will make an offering by fire to Yahweh, a burnt offering, or a sacrifice, to accomplish a vow, or as a freewill offering, or in your set feasts, to make a pleasant aroma to Yahweh, of the herd, or of the flock;

When you prepare a bull for a burnt offering, or for a sacrifice, to accomplish a vow, or for peace offerings to Yahweh;

Israel vowed a vow to Yahweh, and said, "If you will indeed deliver this people into my hand, then I will utterly destroy their cities."

When a man vows a vow to Yahweh, or swears an oath to bind his soul with a bond, he shall not break his word; he shall do according to all that proceeds out of his mouth.

"Also when a woman vows a vow to Yahweh, and binds herself by a bond, being in her father's house, in her youth,

and her father hears her vow, and her bond with which she has bound her soul, and her father holds his peace at her; then all her vows shall stand, and every bond with which she has bound her soul shall stand.

But if her husband disallow her in the day that he hears it, then he shall make void her vow which is on her, and the rash utterance of her lips, with which she has bound her soul: and Yahweh will forgive her.

"But the vow of a widow, or of her who is divorced, [even] everything with which she has bound her soul, shall stand against her.

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