Malachi 2:4-9

4And you will know that I have sent you this warning so that my covenant with Levi may continue,” says the LORD Almighty. 5“My covenant was with him, a covenant of life and peace, and I gave them to him; this called for reverence and he revered me and stood in awe of my name.

6True instruction was in his mouth and nothing false was found on his lips. He walked with me in peace and uprightness, and turned many from sin. 7“For the lips of a priest ought to preserve knowledge, because he is the messenger of the LORD Almighty and people seek instruction from his mouth. 8But you have turned from the way and by your teaching have caused many to stumble; you have violated the covenant with Levi,” says the LORD Almighty.

9“So I have caused you to be despised and humiliated before all the people, because you have not followed my ways but have shown partiality in matters of the law.”
