Bamidbar 6:6-8

Orthodox Jewish Bible

⁶ Kol hayamei of his separation unto Hashem he shall go not near nefesh met (dead body).

⁷ He shall not make himself tameh for his av, or for his em, for his ach, or for his achot, when they die; because the Nezer Elohav (Consecration of his G-d) is upon his head.

⁸ Kol yemei of his nazir (separation) he is kadosh unto Hashem.
