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.

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.

He will act like a refiner and purifier of silver and will cleanse the Levites and refine them like gold and silver. Then they will offer the Lord a proper offering.
