Rules for Priests
21 The Lord said to Moses, “Speak to the priests, the sons of Aaron,(A) and say to them: ‘A priest must not make himself ceremonially unclean(B) for any of his people who die,(C) 2 except for a close relative, such as his mother or father,(D) his son or daughter, his brother, 3 or an unmarried sister who is dependent on him since she has no husband—for her he may make himself unclean.(E) 4 He must not make himself unclean for people related to him by marriage,[a] and so defile himself.
- Leviticus 21:4 Or unclean as a leader among his people
