Numbers 6:5-7

New King James Version

⁵ ‘All the days of the vow of his separation no ^(A)razor shall come upon his head; until the days are fulfilled for which he separated himself to the Lord, he shall be holy. Then he shall let the locks of the hair of his head grow. ⁶ All the days that he separates himself to the Lord ^(B)he shall not go near a dead body. ^7 (C)He shall not ^[a]make himself unclean even for his father or his mother, for his brother or his sister, when they die, because his separation to God is on his head.
