Numbers 6:7-9

Amplified Bible, Classic Edition

⁷ He shall not make himself unclean for his father, mother, brother, or sister, when they die, because his separation and abstinence to his God is upon his head.

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

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