Mal Malachi, chapter Book of Malachi, chapter 3
“And who is bearing the day of His coming? And who is standing in His appearing? For He [is] as fire of a refiner, || And as soap of a fuller. And He has sat, a refiner and purifier of silver, || And He has purified the sons of Levi, || And has refined them as gold and as silver, || And they have been bringing a present near to YHWH in righteousness. Psa 66:10; Isa 1:25; Ezk 22:22
