Malachi 3:2–4

2 But who may 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 shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness. 4 Then shall the offering of Judah and Jerusalem be pleasant unto the LORD, as in the days of old, and as in formera years.
