Numbers 6
3 Ref he shall separate himself from wine and strong drink; he shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any juice of grapes, nor eat fresh grapes or dried.
4 Ref All the days of his separation shall he eat nothing that is made of the grape-vine, from the kernels even to the husk.
5 Ref All the days of his vow of separation there shall no razor come upon his head: until the days be fulfilled, in which he separateth himself unto Jehovah, he shall be holy; he shall let the locks of the hair of his head grow long.
6 Ref All the days that he separateth himself unto Jehovah he shall not come near to a dead body.
7 Ref He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die; because his separation unto God is upon his head.
8 Ref All the days of his separation he is holy unto Jehovah.
