Leviticus 21:1–3

And the Lord said to Moses, “Speak to the priests, the sons of Aaron, and say to them, No one shall make himself unclean for the dead among his people, except for his closest relatives, his mother, his father, his son, his daughter, his brother, or his virgin sister (who is near to him because she has had no husband; for her he may make himself unclean).

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, except for a close relative, such as his mother or father, his son or daughter, his brother, or an unmarried sister who is dependent on him since she has no husband—for her he may make himself unclean.

The Lord said to Moses, “Give the following instructions to the priests, the descendants of Aaron.

“A priest must not make himself ceremonially unclean by touching the dead body of a relative. The only exceptions are his closest relatives—his mother or father, son or daughter, brother, or his virgin sister who depends on him because she has no husband.

Then Yahweh said to Moses, “Speak to the priests, Aaron’s sons, and say to them, ‘One must not make himself unclean for a dead person among his own people, except for his direct relative closest to him: his mother and his father, and his son and his daughter, and his brother, and for his sister, a virgin, who is closest to him, who has not had a husband—for her he may defile himself.

And the Lord said unto Moses, Speak unto the priests the sons of Aaron, and say unto them, There shall none be defiled for the dead among his people: But for his kin, that is near unto him, that is, for his mother, and for his father, and for his son, and for his daughter, and for his brother, And for his sister a virgin, that is nigh unto him, which hath had no husband; for her may he be defiled.
