Leviticus 21:1-4 ▼

1 Then the LORD said to Moses, “Speak to the priests, the sons of Aaron, and say to them: ‘No one shall defile himself [that is, become ceremonially unclean] for the dead among his people [by touching a corpse or assisting in preparing it for burial],

2 except for his relatives who are nearest to him, his mother, his father, his son, his daughter, and his brother,

3 also his virgin sister, who is near to him because she has had no husband; for her he may become unclean.

4 He shall not become unclean as a relative by marriage among his people, and so profane himself.
