Numbers 6:7-9

New Catholic Bible

⁷ He is not to make himself unclean even for his father or mother if they were to die, nor his brother or sister, for the consecration of God is upon his head. ⁸ He is to be holy to the Lord all the days of his vow.

⁹ “ ‘But if someone were to die suddenly in his presence and defile his consecrated head, he is to shave his head on the day of his cleansing and he will shave it again on the seventh day.
