Malachi 2:6-8

6He taught what was true; sinful words were not found on his lips. He walked with me in peace and integrity, and he turned many people away from sin.

7For 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.

8You, 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.
