Numbers 6:3-5

New Catholic Bible

³ that person will abstain from wine and strong drink. He will not drink any vinegar made from wine or from strong drink, nor will he drink any grape juice, nor will he eat grapes or raisins. ⁴ He is not to eat anything that comes from the vine, not even the seeds or the skins as long as he is a Nazirite. ⁵ No razor will touch his head all throughout the time of his vow. He is to be holy until the days of his vow have been completed. He will let the hair on his head grow long.
