³ and for his sister a virgin, that is near unto him, that hath had no husband; for her may he defile himself. ⁴ He shall not defile himself, ^[a]being a chief man among his people, to profane himself. ⁵ They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in their flesh.
