Malachi 2:1-3

“And now this commandment is for you, O priests. If you do not listen, and if you do not take it to heart to give honor to My name,” says the LORD of hosts, “then I will send the curse upon you and I will curse your blessings; and indeed, I have cursed them already, because you are not taking it to heart. Behold, I am going to rebuke your offspring, and I will spread refuse on your faces, the refuse of your feasts; and you will be taken away with it.
