Holiness and the Priests
1 And the Lord said to Moses, “Speak to the priests, the sons of Aaron, and say to them, No one shall cmake himself unclean for the dead among his people, 2 except for his closest relatives, his mother, his father, his son, his daughter, his brother, 3 or his virgin sister (who is near to him because she has had no husband; for her he may make himself unclean). 4 He shall not make himself unclean as a husband among his people and so profane himself.
11 He shall not mgo in to any dead bodies nor make himself unclean, even for his father or for his mother.
25 They shall not ndefile themselves by going near to a dead person. However, for father or mother, for son or daughter, for brother or unmarried sister they may defile themselves.
