Malachi 2:7-9

2:7 For the lips of a priest should preserve knowledge of sacred things, and people should seek instruction from him because he is the messenger of the Lord who rules over all. 2:8 You, however, have turned from the way. You have caused many to violate the law; you have corrupted the covenant with Levi,” says the Lord who rules over all. 2:9 “Therefore, I have caused you to be ignored and belittled before all people to the extent to which you are not following after me and are showing partiality in your instruction.”
