4Then you will know that I have sent you this commandment so that My covenant with Levi may continue,” says the LORD of Hosts.
5“My covenant with him was one of life and peace, which I gave to him; it called for reverence, and he revered Me and stood in awe of My name.
6True instruction was in his mouth, and nothing false was found on his lips. He walked with Me in peace and uprightness, and he turned many from iniquity.
7For the lips of a priest should preserve knowledge, and people should seek instruction from his mouth, because he is the messenger of the LORD of Hosts.
— Malachi 2:4-7
