Leviticus 21:1-3

1Then the Lord said to Moses, “Speak to the priests, the sons of Aaron, and say to them:

aNo one shall defile himself for a dead person among his people,
2 bexcept for his relatives who are nearest to him, his mother and his father and his son and his daughter and his brother, 3also for his virgin sister, who is near to him
Or whom no man has had
because she has had no husband; for her he may defile himself.
