Amplified Bible

^4 [a]All the time of his separation he shall not eat anything produced from the grapevine, from the seeds even to the skins.

⁵ ‘All the time of the vow of his separation no razor shall be used on his head. Until the time of his separation to the Lord is completed, he shall be holy, and shall let the hair of his head grow long.

⁶ ‘All the time that he separates himself to the Lord he shall not go near a dead body.
