Gods Laws - The Making of Vows
A Nazirite must let his hair grow during the period of separation.
Num 6:5 All the days of the vow of his separation, there shall no razor come upon his head: until the days bee 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. KJV 1611
A Nazirite must shave his head and bring the sacrifice when the period of separation is over.
Num 6:13-18 13 And this is the Law of the Nazirite: when the days of his separation are fulfilled, he shall be brought unto the door of the Tabernacle of the Congregation. 14 And he shall offer his offing unto the Lord, one he lamb of the first year without blemish, for a burnt offering, and one ewe lamb of the first year without blemish, for a sin offering, and one lamb without blemish for peace offerings, 15 And a basket of unleavened bread, cakes of fine flour mingled with oil:, and wafers of unleavened bread anointed with oil, and their meat offering, and their drink offerings. 16 And the Priest shall bring them before the Lord, and shall offer his sin offering, and his burnt offering. 17 And he shall offer the ram for a sacrifice of peace offerings unto the Lord, with the basket of unleavened bread: the Priest shall offer also his meat offering, and his drink offering. 18 And the Nazirite shall shave the head of his separation, at the door of the Tabernacle of the Congregation, and shall take the hair of the head of his separation, and put it in the fire which is under the sacrifice of the peace offerings. KJV 1611
The Law of binding and loosing a vow.
Num 30:2-16 2 If a man vow a vow unto the Lord, or swear an othe to bind his soul with a bond: he shall not break his word, he shall doe according to all that proceedeth out of his mouth. 3 If a woman also vow a vow unto the Lord, and bind her self by a bond, being in her fathers house in her youth; 4 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. 5 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. 6 And if she had at all an husband when she vowed, or uttered ought out of her lips, wherewith she bound her soul, 7 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. 8 But if her husband disallow 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. 9 But every vow of a widow, and of her that is divorced, wherewith they have bound their souls, shall stand against her. 10 And if she vowed in her husbands house, or bound her soul by a bond with an oath; 11 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. 12 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. 13 Every vow, and every binding othe to afflict the soul, her husband may establish it, or her husband may make it void. 14 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. 15 But if he shall any ways make them void after that he hath heard them, then he shall bear her iniquity. 16 These are the statutes which the Lord commanded Moses between a man and his wife, between the father and his daughter, being yet in her youth, in her fathers house. KJV 1611
Vows and oaths to The Most High must be kept.
Deut 23:21-23 21 When thou shalt vow a vow unto the Lord thy God, thou shalt not slack to pay it: for the Lord thy God will surely require it of thee; and it would be sin in thee. 22 But if thou shalt forbear to vow, it shall be no sin in thee. 23 That which is gone out of thy lips, thou shalt keep and perform; even a freewill offering according as thou hast vowed unto the Lord thy God, which thou hast promised with thy mouth. KJV 1611
Brother John, I don't get the chance to explore The Book of Numbers and I had to find out who was "The Nazirite."
The root-meaning of the word in Hebrew as well as the various Greek translations indicates the Nazirite as "a consecrated one" or "a devotee." In the circumstances of an ordinary vow, men consecrated some material possession, but the Nazirite consecrated himself or herself, and took a vow of separation and self-imposed discipline for the purpose of some special service, and the fact of the vow was indicated by special signs of abstinence. The chief Old Testament passages are Judges 13:5-7; 16:17; Numbers 6; Amos 2:11,12; compare Sirach 46:13 (Hebrew); 1 Macc 3:49-52.
