Malachi 2:7-9

7For the lips of a priest should guard knowledge, and people should desire instruction from his mouth, because he is the messenger of the Lord of Armies.

8“You, on the other hand, have turned from the way. You have caused many to stumble by your instruction. You have violated the covenant of Levi,” says the Lord of Armies.

9“So I in turn have made you despised and humiliated before all the people because you are not keeping my ways but are showing partiality in your instruction.”
