Malachi 2:4-6

Then you will know that I have sent this commandment to you, that My covenant may continue with Levi,” says the LORD of hosts. “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 stood in awe of My name. True instruction was in his mouth and unrighteousness was not found on his lips; he walked with Me in peace and uprightness, and he turned many back from iniquity.
