Numbers 6:7-9

Evangelical Heritage Version

⁷ He may not defile himself even for his father or his mother or for his brother or his sister when they die, because his sign of separation for God is on his head. ⁸ During the entire time of his separation he is set apart as holy to the Lord.

⁹ If someone near him dies suddenly, thereby defiling the head of hair that marks his separation, he is to shave his head on the day when he is purified. On the seventh day he is to shave it.
