5 All the days of the vow of his separation there shall no rasor come upon his head: until the days be fulfilled, in the which he separateth himself unto the LORD, he shall be holy, and shall let the locks of the hair of his head grow.
6 All the days that he separateth himself unto the LORD he shall come at no dead body.
7 He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God is upon his head.
