Leviticus 10:11

And that ye may teach. — The priests were not only to keep sober to be able to decide the questions of ritual, but they were to teach the people, since the ceremonial law affected domestic life and social intercourse (Deuteronomy 33:10; Malachi 2:7). For neglecting these duties, the prophet charges them : — “Her priests have violated my law, and have profaned my holy things: they have put no difference between the holy and the profane, neither have they showed difference [i.e., taught the people the difference] between the unclean and the clean” (Ezekiel 22:26).
