Malachi 2:7-9

New Catholic Bible

⁷ The lips of a priest should safeguard knowledge,
    and people should seek instruction from his mouth
    because he is the messenger of the Lord of hosts.
⁸ But you have turned aside from the way
    and caused many to stumble
    as the result of your instruction.
You have destroyed the covenant of Levi,
    says the Lord of hosts.
⁹ Therefore, I have made you despised and vile
    in the eyes of all the people,
inasmuch as you have disregarded my ways
    and have not been impartial
    in your interpretation of the law.
