Malachi 2:7-9 For the priest's lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the Lord Almighty.

CAB⁽ⁱ⁾ ⁷ For the priest's lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the Lord Almighty. ⁸ But you have turned aside from the way, and caused many to fail in following the law: you have corrupted the covenant of Levi, says the Lord Almighty. ⁹ And I have made you despised and cast out among all the people, because you have not kept My ways, but have been partial in the law.
