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.
Jewish Publication Society of America Version (JPS1917) - Numbers 6:5 >All the days of his vow of Naziriteship there shall no razor come upon his head; until the days be fulfilled, in which he consecrateth himself unto the LORD, he shall be holy, he shall let the locks of the hair of his head grow long.
