" 'During the entire period of his vow of separation no razor1 may be used on his head.2 He must be holy until the period of his separation to the LORD is over; he must let the hair of his head grow long.
Throughout the period of his separation to the LORD he must not go near a dead body.37
Even if his own father or mother or brother or sister dies, he must not make himself ceremonially unclean4 on account of them, because the symbol of his separation to God is on his head.
Throughout the period of his separation he is consecrated to the LORD.
" 'If someone dies suddenly in his presence, thus defiling the hair he has dedicated,5 he must shave his head on the day of his cleansing6--the seventh day.
