Malachi 2:4-10

4And ye shall know that I have sent this commandment unto you, that my covenant might be with Levi, saith Jehovah of hosts.

5My covenant with him was of life and peace, and I gave them to him that he might fear; and he feared me, and trembled before my name.

6The law of truth was in his mouth, and unrighteousness was not found in his lips: he walked with me in peace and uprightness, and he turned many from iniquity.

7For the priest's lips should keep knowledge, and at his mouth they seek the law; for he is the messenger of Jehovah of hosts.

8But ye are departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith Jehovah of hosts.

9And I also have made you contemptible and base before all the people, because ye have not kept my ways, but have respect of persons in [administering] the law.

10Have we not all one father? Hath not one 1God created us? Why do we deal unfaithfully every man against his brother, by profaning the covenant of our fathers?
