Malachi 2:6

"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 away many from iniquity."

This verse, along with Malachi 2:5,7,8, is given to show Levi's obligation under the covenant of life and peace. What God did here was to cite the provisions of the covenant law that Levi once kept, but that his successors were violating. Clarke has given a summary of these thus:

1. He feared me; he was my sincere worshipper.

2. He acted as in the presence of the just and holy God.

3. The law of God was ever in his mouth.

4. By example and teaching he influenced others.

5. No iniquity proceeded from his lips.

6. He lived in such a manner as to retain his union with God.

7. He turned many away from iniquity.

8. He conducted himself as a true messenger from God.[8]

It is a simple matter to check all of these off one by one, from what is written in this chapter, to see that the Levitical priests of Malachi's time were in total violation of every obligation.
