Numbers 6:7-9

Modern English Version

⁷ He will not defile himself for his father or for his mother, for his brother or for his sister if they die because the separation of his God is on his head. ⁸ All the days of his separation he is holy to the Lord.

⁹ If any man dies very suddenly beside him, and he has defiled his consecrated head, then he will shave his head in the day of his cleansing, on the seventh day will he shave it.
