“Therefore, this decree is for you priests: If you don’t listen, and if you don’t take it to heart to honor my name,” says the LORD of Armies, “I will send a curse among you, and I will curse your blessings. In fact, I have already begun to curse them because you are not taking it to heart.
“Look, I am going to rebuke your descendants, and I will spread animal waste over your faces, the waste from your festival sacrifices, and you will be taken away with it. Then you will know that I sent you this decree, so that my covenant with Levi may continue,” says the LORD of Armies. “My covenant with him was one of life and peace, and I gave these to him; it called for reverence, and he revered me and stood in awe of my name. True instruction was in his mouth, and nothing wrong was found on his lips. He walked with me in peace and integrity and turned many from iniquity. For the lips of a priest should guard knowledge, and people should desire instruction from his mouth, because he is the messenger of the LORD of Armies.
“You, on the other hand, have turned from the way. You have caused many to stumble by your instruction. You have violated the covenant of Levi,” says the LORD of Armies. “So I in turn have made you despised and humiliated before all the people because you are not keeping my ways but are showing partiality in your instruction.”
