Numbers 6:6

⁴  All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk.

⁵  All the days of the vow of his separation there shall no razor 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.

⁸  All the days of his separation he is holy unto the LORD.
