Bible Verses About The Dead: A priest not to mourn for, except when near of kin

ADONAI said to Moshe, "Speak to the cohanim, the sons of Aharon; tell them: 'No cohen is to make himself unclean for any of his people who dies,

except for his close relatives -his mother, father, son, daughter and brother;

he may also make himself unclean for his virgin sister who has never married and is therefore dependent on him.
