Leviticus 21:1-4 ▼

1 The LORD said to Moses, “Speak to Aaron’s sons, the priests, and tell them: A priest is not to make himself ceremonially unclean for a dead person among his relatives,

2 except for his immediate family: his mother, father, son, daughter, or brother.

3 He may make himself unclean for his unmarried virgin sister in his immediate family.

4 He is not to make himself unclean for those related to him by marriage and so defile himself.
