Her priests - whose “lips should have kept knowledge” (Mal 2:7).
violated - not simply transgressed; but, have done violence to the law, by wresting it to wrong ends, and putting wrong constructions on it.
put no difference between the holy and profane, etc. - made no distinction between the clean and unclean (Lev 10:10), the Sabbath and other days, sanctioning violations of that holy day. “Holy” means, what is dedicated to God; “profane,” what is in common use; “unclean,” what is forbidden to be eaten; “clean,” what is lawful to be eaten.
I am profaned among them - They abuse My name to false or unjust purposes.
