Bible Verses About Defilement: Mourning for the dead

And Jehovah saith unto Moses, `Speak unto the priests, sons of Aaron, and thou hast said unto them, For any person a priest is not defiled among his people,

except for his relation who is near unto him--for his mother, and for his father, and for his son, and for his daughter, and for his brother.

and for his sister, the virgin, who is near unto him, who hath not been to a man; for her he is defiled.
