Numbers 6:4-5

All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk. {separation: or, Nazariteship} {vine...: Heb. vine of the wine} 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.
