Malachi 3:2-4

ISV(i) 2 But who will survive the day when he comes? Or who can stand when he appears? Because he’s like a refiner’s fire and a launderer’s soap, 3 he will sit refining and purifying silver, purifying the descendants of Levi, refining them like gold and silver. Then they’ll bring a righteous offering to the LORD. 4 Then the offering to the LORD by Judah and Jerusalem will be acceptable as it was in the past, even as in former years.
