23 “‘And my people they should instruct in the difference between a holy thing and a profane thing; and the difference between what is unclean and what is clean they should cause them to know.+
7 For the lips of a priest are the ones that should keep knowledge, and [the] law is what people should seek from his mouth;+ for he is the messenger* of Jehovah of armies.+
9 holding firmly to the faithful word as respects his [art of] teaching,+ that he may be able both to exhort by the teaching that is healthful+ and to reprove+ those who contradict.
