The LORD said to Moses, “Speak to the priests, the sons of Aaron, and say to them, ‘A priest shall not defile himself for the dead among his people, except for his relatives that are near to him: for his mother, for his father, for his son, for his daughter, for his brother, and for his virgin sister who is near to him, who has had no husband; for her he may defile himself.
He shall not defile himself, being a chief man among his people, to profane himself.
“‘They shall not shave their heads or shave off the corners of their beards or make any cuttings in their flesh.
