Malachi 3:2-4 American Standard Version (ASV)
2 But who can abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner’s fire, and like fullers’ soap: 3 and he will sit as a refiner and purifier of silver, and he will purify the sons of Levi, and refine them as gold and silver; and they shall offer unto Jehovah offerings in righteousness. 4 Then shall the offering of Judah and Jerusalem be pleasant unto Jehovah, as in the days of old, and as in ancient years.
