Malachi 2:2-3

2:2 If you do not listen and take seriously the need to honor my name,” says the Lord who rules over all, “I will send judgment on you and turn your blessings into curses – indeed, I have already done so because you are not taking it to heart. 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.
