Numbers 6:5-7

Revised Standard Version Catholic Edition

⁵ “All the days of his vow of separation no razor shall come upon his head; until the time is completed for which he separates himself to the Lord, he shall be holy; he shall let the locks of hair of his head grow long.

⁶ “All the days that he separates himself to the Lord he shall not go near a dead body. ⁷ Neither for his father nor for his mother, nor for brother or sister, if they die, shall he make himself unclean; because his separation to God is upon his head.
