Malachi 2:4-8

Then you will know that I have sent this commandment to you, so that My covenant may continue with Levi,” says the Lord of armies.

“My covenant with him was one of life and peace, and I gave them to him as an object of reverence; so he revered Me and was in awe of My name.

True instruction was in his mouth and injustice was not found on his lips; he walked with Me in peace and justice, and he turned many back from wrongdoing.

For the lips of a priest should maintain knowledge, and people should seek instruction from his mouth; for he is the messenger of the Lord of armies.

But as for you, you have turned aside from the way; you have caused many to stumble by the instruction; you have ruined the covenant of Levi,” says the Lord of armies.
