The term Nazirite
transliterates the Hebrew nāzîr (נזיר), from the root nzr (נזר), meaning as a verb to separate
or to hold oneself back from,
and as a noun consecration
or dedication.

Though the time of the Nazirite vow’s institution is not known, it appears for the first time in the Scriptures in Numbers 6:1–21, the only passage in the Bible outlining the conduct for one wanting to become a Nazirite. Nazirites were separated in two ways: negatively, they were separated from three things: 1) wine, strong drink, grapes, and raisins; 2) the cutting of the hair or beard during the vow’s duration; and 3) contact with corpses and graves, including those of a family member. Positively, they were separated uniquely to the Lord, holy to the Lord
(Numbers 6).
5 for behold, you shall conceive and bear a son. No razor shall come upon his head, for the child shall be a Nazirite to God from the womb, and he shall begin to save Israel from the hand of the Philistines.”
