Leviticus 21:3 BBE

¹  And the Lord said to Moses, Say to the priests, the sons of Aaron, Let no man make himself unclean for the dead among his people;

²  But only for his near relations, for his mother or his father, his son or his daughter, and his brother;

³  And for his sister, a virgin, for she is his near relation and has had no husband, he may make himself unclean.

⁴  But let him, being a chief among his people, not make himself unclean in such a way as to put shame on himself.

⁵  They are not to have their hair cut off for the dead, or the hair on their chins cut short, or make cuts in their flesh.
