'Consecration' in the Bible

During the entire time of his dedication, he is not to allow a razor to pass over his head until the days of his holy consecration to the LORD have been fulfilled. He is to let the locks on his head grow long.

He is not to defile himself on account of his father, mother, brother, and sister when they die, because the crown of his consecration to God is on his head.

He is to dedicate to the LORD the days of his consecration by bringing a year old male lamb as his offering. The previous time will have failed because his consecration became defiled.

"This is the law of the Nazirite: When the days of his consecration are completed, he is to come to the entrance at 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 to be the law of the Nazirite when he commits his offering to the LORD on account of his consecration, over and beyond what he owns alone plus whatever he can provide, based on the vow from his own mouth that he vows to fulfill on account of the law of his consecration."
