Malachi 2:4-11

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. For the priest’s lips should keep knowledge, and they should seek the law at his mouth; for he is the messenger of Jehovah of hosts. But ye are turned aside out of the way; ye have caused many to stumble in the law; ye have corrupted the covenant of Levi, saith Jehovah of hosts. Therefore have I also made you contemptible and base before all the people, according as ye have not kept my ways, but have had respect of persons in the law. Have we not all one father? hath not one God created us? why do we deal treacherously every man against his brother, profaning the covenant of our fathers? Judah hath dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah hath profaned the holiness of Jehovah which he loveth, and hath married the daughter of a foreign god.
