Malachi 2:8-10 New Revised Standard Version (NRSV)
8 But you have turned aside from the way; you have caused many to stumble by your instruction; you have corrupted the covenant of Levi, says the Lord of hosts, 9 and so I make you despised and abased before all the people, inasmuch as you have not kept my ways but have shown partiality in your instruction.
The Covenant Profaned by Judah
10 Have we not all one father? Has not one God created us? Why then are we faithless to one another, profaning the covenant of our ancestors?
