Malachi 2:1-10

“And now, O priests, this command is for you. If you will not listen, if you will not take it to heart to give honor to my name, says the LORD of hosts, then I will send the curse upon you and I will curse your blessings. Indeed, I have already cursed them, because you do not lay it to heart. Behold, I will rebuke your offspring, and spread dung on your faces, the dung of your offerings, and you shall be taken away with it. So shall you know that I have sent this command to you, that my covenant with Levi may stand, says the LORD of hosts. My 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. True 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. 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. 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, and 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.” Have we not all one Father? Has not one God created us? Why then are we faithless to one another, profaning the covenant of our fathers?
