Malachi 2:6-14

True instruction was in his mouth, and nothing wrong was found on his lips. He walked with me  in peace and integrity and turned many from iniquity.  For the lips of a priest should guard knowledge, and people should desire instruction from his mouth, because he is the messenger of the LORD of Armies.  “You, on the other hand, have turned from the way.  You have caused many to stumble  by your instruction. You have violated  the covenant of Levi,” says the LORD of Armies. “So I in turn have made you despised  and humiliated before all the people because you are not keeping my ways but are showing partiality in your instruction.”  Don’t all of us have one Father?  Didn’t one God create us?  Why then do we act treacherously against one another,  profaning  the covenant of our ancestors?  Judah has acted treacherously, and a detestable  act has been done in Israel and in Jerusalem. For Judah has profaned  the LORD’s sanctuary,  , which he loves,  and has married the daughter of a foreign god.  , May the LORD cut off  from the tents of Jacob the man who does this, whoever he may be,  , even if he presents an offering to the LORD of Armies. This is another thing you do. You are covering the LORD’s altar with tears, with weeping and groaning,  because he no longer respects your offerings or receives them gladly from your hands.  And you ask, “Why? ” Because even though the LORD has been a witness  between you and the wife of your youth,  you have acted treacherously against her. She was your marriage partner  and your wife by covenant.
