'Hair' in the Bible

After the priest has the woman stand before the Lord, he is to let down her hair and place in her hands the grain offering for remembrance, which is the grain offering of jealousy. The priest is to hold the bitter water that brings a curse.

“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 not to defile himself for his father or mother, or his brother or sister, when they die, because the hair consecrated to his God is on his head.

“If someone suddenly dies near him, defiling his consecrated head of hair, he must shave his head on the day of his purification; he is to shave it on the seventh day.

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.

“The Nazirite is to shave his consecrated head at the entrance to the tent of meeting, take the hair from his head, and put it on the fire under the fellowship sacrifice.

Also purify everything: garments, leather goods, things made of goat hair, and every article of wood.”
