Parallel
Numbers 6:5
Jewish Publication Society 1917 · Berean Standard Bible
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.
For the entire period of his vow of separation, no razor shall touch his head. He must be holy until the time of his separation to the LORD is complete; he must let the hair of his head grow long.
