Malachi 3:2-4

New Revised Standard Version, Anglicised

² But who can endure the day of his coming, and who can stand when he appears?

For he is like a refiner’s fire and like fullers’ soap; ³ he will sit as a refiner and purifier of silver, and he will purify the descendants of Levi and refine them like gold and silver, until they present offerings to the Lord in righteousness.^{[a] 4} Then the offering of Judah and Jerusalem will be pleasing to the Lord as in the days of old and as in former years.
