Leviticus 21:1-4 ▼

1 The LORD said to Moses, “Speak to the priests, the sons of Aaron, and say to them: ‘A priest must not make himself ceremonially unclean for any of his people who die,

2 except for a close relative, such as his mother or father, 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.

4 He must not make himself unclean for people related to him by marriage, and so defile himself.
