'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 is holy to the Lord during the time of consecration.

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.

“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.”
