Ezekiel 44:24-26

New Catholic Bible

²⁴ In any dispute, the priests are to serve as judges, and they shall render their decisions according to my decrees. They must observe my laws and my statutes for all of my appointed feasts, and they shall keep my Sabbaths holy.

²⁵ Priests may not make themselves unclean by coming near a dead person. However, if the deceased is a father or mother, son or daughter, brother or unmarried sister, then they are permitted to defile themselves. ²⁶ After such a priest has been purified, he must wait a further seven days.
