Ezekiel 44:25-27

New Century Version

²⁵ “‘They must not go near a dead person, making themselves unclean. But they are allowed to make themselves unclean if the dead person is their father, mother, son, daughter, brother, or a sister who has not married. ²⁶ After a priest has been made clean again, he must wait seven days. ²⁷ Then he may go into the inner courtyard to serve in the Temple, but he must offer a sin offering for himself, says the Lord God.
