Teaching between what is holy and what is not

LEVITICUS 10:10-11 NKJV
10   "that you may distinguish between holy and unholy, and between unclean and clean,
11   "and that you may teach the children of Israel all the statutes which the Lord has spoken to
them by the hand of Moses."

EZEKIEL 22:26 NKJV
     "Her priests have violated My law and profaned My holy things;they have not distinguished
between the holy and the unholy, nor have they made known the difference between the unclean
and the clean; and they have hidden their eyes from My Sabbaths, so that I am profaned among
them.

EZEKIEL 44:23-24 NKJV
23   "And they shall teach My people the difference between the holy and the unholy, and cause
them to discern between the unclean and the clean.
24   "In controversy they shall stand as judges, and judge it according to My judgements. They
shall keep My laws and My statutes in all My appointed meetings, and they shall hallow My
Sabbaths.
