Malachi 2:4-6

And ye shall know that I have sent this commandment unto you, that my covenant may be with Levi, saith Jehovah of hosts. My covenant was with him of life and peace; and I gave them to him that he might fear; and he feared me, and stood in awe of my name. The 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.
