Malachi 3:3-4

Common English Bible

³ He will sit as a refiner and a purifier of silver.
        He will purify the Levites
            and refine them like gold and silver.
            They will belong to the Lord,
                presenting a righteous offering.
⁴ The offering of Judah and Jerusalem will be pleasing to the Lord
        as in ancient days and in former years.
