Malachi 2:2-3
If you do not listen, and if you do not resolve to honor my name,” says the LORD Almighty, “I will send a curse on you, and I will curse your blessings. Yes, I have already cursed them, because you have not resolved to honor me.

“Because of you I will rebuke your descendants; I will smear on your faces the dung from your festival sacrifices, and you will be carried off with it.
