Malachi 2:3-4

2:3 I am about to discipline your children and will spread offal on your faces, the very offal produced at your festivals, and you will be carried away along with it. 2:4 Then you will know that I sent this commandment to you so that my covenant may continue to be with Levi,” says the Lord who rules over all.

Malachi 2:8-9

2:8 You, however, have turned from the way. You have caused many to violate the law; you have corrupted the covenant with Levi,” says the Lord who rules over all. 2:9 “Therefore, I have caused you to be ignored and belittled before all people to the extent to which you are not following after me and are showing partiality in your instruction.”
