Malachi 2:7-9

New Revised Standard Version, Anglicised

⁷ For the lips of a priest should guard knowledge, and people should seek instruction from his mouth, for he is the messenger of the Lord of hosts. ⁸ But you have turned aside from the way; you have caused many to stumble by your instruction; you have corrupted the covenant of Levi, says the Lord of hosts, ⁹ and so I make you despised and abased before all the people, inasmuch as you have not kept my ways but have shown partiality in your instruction.
