Malachi 2:1-3

1The Lord Almighty says this to the priests:

2‘Listen carefully to what I say to you. You must respect my name properly. If not, I will punish you. I will no longer bless you but I will curse you. I am already doing that because you do not respect my name as you should.

3I will punish your descendants. When you offer an animal as a sacrifice at your festivals, I will cover your faces with its dirty bits. Then they will throw you away with all the other dirty bits. Those are the bits that I cannot accept as clean.’
