Bamidbar 6:7-9

Orthodox Jewish Bible

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.

⁹ And if any man die very suddenly by him, and he hath made tameh the head of his nezer (consecration); then he shall shave his head in the yom of his tohorat, on the yom hashevi’i shall he shave it.
