Malachi 2:4-7

4Then you shall know that I have sent this commandment to you, That My covenant with Levi may continue,” Says the Lord of hosts.

5“My covenant was with him, one of life and peace, And I gave them to him that he might fear Me; So he feared Me And was reverent before My name.

6The law of truth was in his mouth, And injustice was not found on his lips. He walked with Me in peace and equity, And turned many away from iniquity.

7“For the lips of a priest should keep knowledge, And people should seek the law from his mouth; For he is the messenger of the Lord of hosts.
