Malachi 3:2-4 World English Bible (WEB)
2 “But who can endure the day of his coming? And who will stand when he appears? For he is like a refiner’s fire, and like launderers’ 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 to Yahweh offerings in righteousness. 4 Then the offering of Judah and Jerusalem will be pleasant to Yahweh, as in the days of old, and as in ancient years.
