Mal Malachi, chapter Book of Malachi, chapter 3
“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; 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. Psa 66:10; Isa 1:25; Ezk 22:22
