Malachi 3:3-4

And he shall sit as a refiner He shall be diligently employed in his office, in performing which he shall resemble a refiner and purifier of silver. And he shall purify the sons of Levi And whereas the misconduct of the sons of Levi has been very great, (particularly of those who have been taken notice of and reproved in the foregoing Chapter s,) the Messiah when he comes will reform these abuses, and purify the worship of God from such corruptions. And purge them as gold and silver The effect of this fiery trial, and purifying furnace, shall be the thorough cleansing of the persons that are to pass through it. Not all the sons of Levi, says Houbigant, “for the similitude is taken from gold and silver, which being purified there remains some dross behind. So it happened after the ministration of Jesus Christ: a great company of the priests were obedient to the faith, Acts 6:7. Of the other sons of Levi, who did not believe in Christ, it is just before said, Who may abide the day of his coming, when, the metal being purified, he will cast the dross into the fire.” But those who should minister in holy things in the Christian Church, instead of the Levitical priests, are chiefly intended: or rather, all real Christians, who are made a holy priesthood, and who, with hearts and minds purified by faith, offer up spiritual sacrifices acceptable to God by Jesus Christ, 1 Peter 2:5; yea, who even offer themselves, their souls and bodies, their faculties and members, their time and talents, all they are and have, unto the Lord an offering in righteousness. Then shall the offering of Judah and Jerusalem The services and duties of the Christian ministry, and of the whole Christian Church; be pleasant unto the Lord Acceptable and even well pleasing to him. The prophet describes the Christian worship, and the various services of the Christian Church, and of its true members, by expressions taken from the Jewish service, being that with which they were acquainted; as in the days of old As in the purest ages of the patriarchal or Mosaic dispensation, or, as in the times of Abraham, Isaac, Jacob, Samuel, David.
