'Nazirite' in the Bible

“Speak to the sons of Israel and say to them, ‘When a man or woman makes a special vow, the vow of a Nazirite, to dedicate himself to the Lord,

and shall dedicate to the Lord his days as a Nazirite, and shall bring a male lamb a year old for a guilt offering; but the former days will be void because his separation was defiled.

‘Now this is the law of the Nazirite when the days of his separation are fulfilled, he shall bring the offering to the doorway of the tent of meeting.

The Nazirite shall then shave his dedicated head of hair at the doorway of the tent of meeting, and take the dedicated hair of his head and put it on the fire which is under the sacrifice of peace offerings.

The priest shall take the ram’s shoulder when it has been boiled, and one unleavened cake out of the basket and one unleavened wafer, and shall put them on the hands of the Nazirite after he has shaved his dedicated hair.

Then the priest shall wave them for a wave offering before the Lord. It is holy for the priest, together with the breast offered by waving and the thigh offered by lifting up; and afterward the Nazirite may drink wine.’

“This is the law of the Nazirite who vows his offering to the Lord according to his separation, in addition to what else he can afford; according to his vow which he takes, so he shall do according to the law of his separation.”

For behold, you shall conceive and give birth to a son, and no razor shall come upon his head, for the boy shall be a Nazirite to God from the womb; and he shall begin to deliver Israel from the hands of the Philistines.”

But he said to me, ‘Behold, you shall conceive and give birth to a son, and now you shall not drink wine or strong drink nor eat any unclean thing, for the boy shall be a Nazirite to God from the womb to the day of his death.’”

So he told her all that was in his heart and said to her, “A razor has never come on my head, for I have been a Nazirite to God from my mother’s womb. If I am shaved, then my strength will leave me and I will become weak and be like any other man.”
