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.
King James Version (KJV):
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.
