Leviticus 21:1 ASV

¹  And Jehovah said unto Moses, Speak unto the priests, the sons of Aaron, and say unto them, There shall none defile himself for the dead among his people;

²  except for his kin, that is near unto him, for his mother, and for his father, and for his son, and for his daughter, and for his brother,

³  and for his sister a virgin, that is near unto him, that hath had no husband; for her may he defile himself.
