Ezekiel 44:23-25

New Revised Standard Version Catholic Edition

²³ They shall teach my people the difference between the holy and the common, and show them how to distinguish between the unclean and the clean. ²⁴ In a controversy they shall act as judges, and they shall decide it according to my judgments. They shall keep my laws and my statutes regarding all my appointed festivals, and they shall keep my sabbaths holy. ²⁵ They shall not defile themselves by going near to a dead person; for father or mother, however, and for son or daughter, and for brother or unmarried sister they may defile themselves.
