Malachi 3:2-3 And who measures the day of his coming? And who stands when he is seen? - for he is as the fire of a refiner and as the soap of a fullers:

ECB⁽ⁱ⁾ ² And who measures the day of his coming? And who stands when he is seen? - for he is as the fire of a refiner and as the soap of a fullers: ³ and he sits as a refiner and purifier of silver: and he purifies the sons of Levi and purges them as gold and silver, so that they bring near an offering in justness to Yah Veh.
