Now, though there were many Nazarites, the only Biblical characters who were lifelong Nazarites were Samson, Samuel, and John the Baptist (Judges 13:4-5, I Samuel 1:11 and Luke 1:15). Temporary Nazarites were more common. Even the apostle Paul evidently took a couple of temporary Nazarite vows upon himself.
A Nazarite vow allowed Jews who were not of the tribe of Levi to approach closer to God than they could have done otherwise. Of course, Samson is the most famous (and infamous) of all of the Nazarites. What with his long hair, superhuman strength, womanizing and strange death, he was certainly an intriguing character. But, truly, all Nazarites... even Samson... were such for one reason and one reason only. Though it might not be immediately apparent ... every Nazarite was a Nazarite in order to point to The Nazarene. Not by their title; but by their separation (Hebrews 7:26).
