Malachi 3:1-3

New Revised Standard Version, Anglicised Catholic Edition

The Coming Messenger

3 See, I am sending my messenger to prepare the way before me, and the Lord whom you seek will suddenly come to his temple. The messenger of the covenant in whom you delight—indeed, he is coming, says the Lord of hosts. 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]
