Ezekiel 44:25-27

New Catholic Bible

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. ²⁷ On the day that he enters the inner court of the sanctuary to minister in the sanctuary, he shall offer a sin offering for himself, says the Lord God.
