Numbers 6:7-9

Darby Translation

⁷ He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister when they die; for the consecration of his God is upon his head.

⁸ All the days of his separation he is holy to Jehovah.

⁹ And if any one die unexpectedly by him suddenly, and he hath defiled the head of his consecration, then he shall shave his head on the day of his cleansing; on the seventh day shall he shave it.
