'Consecration' in the Bible
“You must not cut his hair throughout the time of his vow of consecration. He must be holy until the time is completed during which he consecrates himself to the Lord; he is to let the hair of his head grow long.
He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God is upon his head.
And if any man die very suddenly by him, and he hath defiled the head of his consecration; then he shall shave his head in the day of his cleansing, on the seventh day shall he shave it.
He is to rededicate his time of consecration to the Lord and to bring a year-old male lamb as a restitution offering. But do not count the previous period, because his consecrated hair became defiled.
“This is the law of the Nazirite: On the day his time of consecration is completed, he must be brought to the entrance to the tent of meeting.
The Nazirite is then to shave his head of consecration at the entrance to the Tent of Meeting. He is to take the lock of his head of consecration and set it over the fire where the peace offering for sacrifice is.
Then the priest is to take the boiled shoulder of the ram, one cake of unleavened bread from the basket, and one wafer of unleavened bread. He is to place them in the hands of the Nazirite, after he himself has shaved his symbol of consecration.
“This is the ritual of the Nazirite who vows his offering to the Lord for his consecration, in addition to whatever else he can afford; he must fulfill whatever vow he makes in keeping with the ritual for his consecration.”
