'Nazirite' 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,

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 tent of meeting:

And the Nazirite shall shave the head of his separation at the door of the tent of meeting, and shall take the hair of the head of his separation, and put it on the fire which is under the sacrifice of peace-offerings.

And the priest shall take the boiled shoulder of the ram, and one unleavened cake out of the basket, and one unleavened wafer, and shall put them upon the hands of the Nazirite, after he hath shaven the head of his separation;

and the priest shall wave them for a wave-offering before Jehovah; this is holy for the priest, together with the wave-breast and heave-thigh: and after that the Nazirite may drink wine.

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.

for, lo, thou shalt conceive, and bear a son; and no razor shall come upon his head; for the child shall be a Nazirite unto God from the womb: and he shall begin to save Israel out of the hand of the Philistines.

but he said unto me, Behold, thou shalt conceive, and bear a son; and now drink no wine nor strong drink, and eat not any unclean thing; for the child shall be a Nazirite unto God from the womb to the day of his death.

And he told her all his heart, and said unto her, There hath not come a razor upon my head; for I have been a Nazirite unto God from my mother's womb: if I be shaven, then my strength will go from me, and I shall become weak, and be like any other man.
