Numbers 6:7-9

Revised Standard Version

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

⁹ “And if any man dies very suddenly beside him, and he defiles his consecrated head, then he shall shave his head on the day of his cleansing; on the seventh day he shall shave it.
