WHO WERE THE NAZIRITES? Part 1.

A Nazi'Rite was a dedicated, separated, or single out individual trained to perform a specific task.
There were 2 classes of Nazi'Rites: those who volunteered and those who were such by divine appointment. Either men or women could take THE VOW to GOD to live as Naza'Rites for a period of time. However, if a daughter's father or a wife's husband heard the vows of their respective females, they could cancel the vows if they did not approve. (Numbers 30: 1-8)
The regulations governing volunteer Nazi'Rites are found in the Book of Numbers.
NUMBER 6: "Any of you, male or female, who MAKE A SPECIAL VOW to become a Nazi'Rite and DEDICATE YOURSELF TO the LORD shall ABSTAIN FROM WINE and BEER. You shall not drink any kind of drink made from grapes or eat any grapes or raisins. As long as you are a Nazi'Rite, you shall not eat anything that comes from a grapevine, not even the seeds or skins of grapes.
As long as YOU ARE UNDER the Nazi'Rite VOW, you MUST NOT CUT YOUR HAIR OR SHAVE. You are BOUND BY THE VOW FOR THE FULL TIME that YOU ARE DEDICATED TO THE LORD, and you shall let your hair grow. YOUR HAIR IS THE SIGN of your dedication TO GOD, and YOU MUST NOT DEFILE YOURSELF BY GOING NEAR A CORPSE, not even that of your father, mother, brother, or sister. YOU ARE CONSECRATED TO THE LORD.
IF your CONSECRATED HAIR IS DEFILED because you are right beside someone who suddenly dies, YOU MUST WAIT 7 DAYS and then SHAVE YOUR HEAD; and so YOU BECOME ritually CLEAN. On the 8TH day you shall BRING 2 DOVES OR 2 PIGEONS TO the PRIEST AT the ENTRANCE OF the TENT of the LORD's PRESENCE. The PRIEST shall OFFER ONE AS a SIN OFFERING and THE OTHER AS a BURNT OFFERING, to perform the ritual PURIFICATION FOR YOU because OF YOUR CONTACT WITH A CORPSE. On the SAME DAY YOU SHALL RE-CONSECRATE YOUR HAIR and REDEDICATE TO THE LORD YOUR TIME AS A NAZI'RITE. The PREVIOUS PERIOD OF TIME DOES NOT COUNT, because your consecrated hair was defiled. AS A REPAYMENT OFFERING you shall BRING a 1YEAR OLD LAMB.
The person taking this Special Vow was meant "to live as a Naza'Rite to GOD," that is dedicated, separated from the way of the World and gaining spiritual strength to serve GOD and be able to stand close to HIM. It was not meant to be for the plaudits of men due to a showy display of fanatical asceticism. The requirements laid on the Nazi'Rites had special significance in the unseen world, and deep meaning in the Worship of GOD. Like the High Priest who, because of his Holy Office, was to touch no dead body, even that of his closest relatives, so too the Nazi'Rite. The High Priest as well as the under priests, due to the serious responsibility of their offices in the unseen World, were forbidden to drink the wine of the World or intoxicating liquor when performing their sacred duties before GOD.
(Leviticus 10:8-11; 21:10,11)
Furthermore, the Nazi'Rite "should prove Holy by letting the locks of the hair of his head grow," such serving as a crowning sign of his spiritual strength by which all could quickly recognize his Holy Nazi'riteship. The same Hebrew word "Nazir" was used in regard to the spiritual significance about the "unpruned" vines during the Sacred Sabbath and Jubilee Years. (Leviticus 25:5,11) Also the gold plate on the front of the turban of the High Priest, engraved with the Words "HOLINESS BELONG TO GOD," was called "the holy sign of dedication" coming from the same Hebrew root word "Nazir." (Exodus 39:30, 31) Likewise, the official headpiece or diadem worn by Israel's anointed kings was also called a "Nezer." (2 Samuel 1:10; 2 Kings 11:12)
When the specified duration of the VOW CAME TO AN END, the Nazi'Rite presented himself to the priests before the Tent of Meeting, bringing along the prescribed sacrifices consisting of a Young Ram for a Burnt Offering, a Female Lamb for a Sin Offering, and a Ram for a Communion Sacrifice. He also was to bring a basket of unfermented (unleavened) cakes and wafers that were well oiled, together with the proper grain and drink offerings. In addition to these necessary sacrifices, the Nazi'Rite brought such other offerings to the sanctuary as he could afford. Next, the NAZI'RITE HAD THE LONG HAIR CUT OFF and it was PLACED ON THE FIRE UNDER THE COMMUNION SACRIFICE, and then portions of the offerings were placed in his hands by the officiating Priest and WAVED BY THE PRIEST AS A WAVE OFFERING BEFORE GOD.
It appears that in time spiritually wealthy individuals were able to provide the necessary means for  sacrifices as an act of charity, for persons of little means. This seemed to be the recognized custom that the apostle Paul took advantage of upon arriving in JERUSALEM at the end of his 3rd tour. To allay the false rumors that Paul had been "teaching all the Jews among the nations ... not to walk in the solemn customs" of the Jewish nation, Paul's Christian brothers recommended the following plan.
"We have 4 men with a Vow upon themselves," they told Paul, "Take  these men along and cleanse yourself ceremonially with them and take care of their expenses, that they may have their heads shaved." (Acts 21: 20-26)
