A Covenant of Life & Peace With Levi

Malachi 2:4-6

4  And ye shall know that I have sent this commandment unto you, that my covenant might be with Levi, saith the LORD of hosts. 
5  My covenant was with him of life and peace; and I gave them to him for the fear wherewith he feared me, and was afraid before my name. 
6  The law of truth was in his mouth, and iniquity was not found in his lips: he walked with me in peace and equity, and did turn many away from iniquity.
