Malachi 2:4-9

4So shall you know that I have sent this command to you, that my covenant with Levi may stand, says the LORD of hosts. 5My covenant with him was one of life and peace, and I gave them to him. It was a covenant of fear, and he feared me. He stood in awe of my name. 6True instruction was in his mouth, and no wrong was found on his lips. He walked with me in peace and uprightness, and he turned many from iniquity. 7For 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. 8But 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, 9and so I make you despised and abased before all the people, inasmuch as you do not keep my ways but show partiality in your instruction.”
