'Law of the Nazirite' in the Bible

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:

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.
