Leviticus 21:1-5

1The Lord spoke to Moses, “Tell the priests, Aaron’s sons: None of you should become unclean by touching one of your relatives who has died.

2However, you are allowed to become unclean when one of your nearest relatives dies. These relatives include your mother, father, son, daughter, or brother,

3and especially an unmarried virgin sister who is still close to you.

4As the head of your people, you should never become unclean. That would make you unholy.

5“You should never mourn by shaving bald spots on your heads, shaving the edges of your beards, or slashing your bodies.
