'Vow' in the Bible

Speak unto the children of Israel, and say unto them, When either man or woman shall make a special vow, the vow of a Nazirite, to separate himself unto Jehovah,

All the days of his vow of separation there shall no razor come upon his head: until the days be fulfilled, in which he separateth himself unto Jehovah, 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 voweth, and of his oblation unto Jehovah for his separation, besides that which he is able to get: according to his vow which he voweth, so he must do after the law of his separation.

and will make an offering by fire unto Jehovah, a burnt-offering, or a sacrifice, to accomplish a vow, or as a freewill-offering, or in your set feasts, to make a sweet savor unto Jehovah, of the herd, or of the flock;

And when thou preparest a bullock for a burnt-offering, or for a sacrifice, to accomplish a vow, or for peace-offerings unto Jehovah;

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

When a man voweth a vow unto Jehovah, or sweareth 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.

Also when a woman voweth a vow unto Jehovah, and bindeth herself by a bond, being in her father's house, in her youth,

and her father heareth her vow, and her bond wherewith she hath bound her soul, and her father holdeth his peace at her; then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand.

But if her husband disallow her in the day that he heareth it, then he shall make void her vow which is upon her, and the rash utterance of her lips, wherewith she hath bound her soul: and Jehovah will forgive her.

But the vow of a widow, or of her that is divorced, even everything wherewith she hath 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.
