Malachi 2:1-9

1 “And now, you priests, this warning is for you.
2 If you do not listen, and if you do not resolve to honor my name,” says the LORD Almighty, “I will send a curse on you, and I will curse your blessings. Yes, I have already cursed them, because you have not resolved to honor me.
3 “Because of you I will rebuke your descendants; I will smear on your faces the dung from your festival sacrifices, and you will be carried off with it.
4 And 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.
6 True 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.
8 But 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.”
