Malachi 2:5

1“Now, you priests, this commandment is for you.

2If you will not listen, and if you will not take it to heart, to give glory to my name,” says the LORD of Armies, “then I will send the curse on you, and I will curse your blessings. Indeed, I have cursed them already, because you do not take it to heart.

3Behold, I will rebuke your offspring, and will spread dung on your faces, even the dung of your feasts; and you will be taken away with it.

4You will know that I have sent this commandment to you, that my covenant may be with Levi,” says the LORD of Armies.

5“My covenant was with him of life and peace; and I gave them to him that he might be reverent toward me; and he was reverent toward me, and stood in awe of my name.

6The law of truth was in his mouth, and unrighteousness was not found in his lips. He walked with me in peace and uprightness, and turned many away from iniquity.

7For the priest’s lips should keep knowledge, and they should seek the law at his mouth; for he is the messenger of the LORD of Armies.

8But you have turned away from the path. You have caused many to stumble in the law. You have corrupted the covenant of Levi,” says the LORD of Armies.

9“Therefore I have also made you contemptible and wicked before all the people, according to the way you have not kept my ways, but have had respect for persons in the law.
