Malachi 3:1-3 New English Translation (NET Bible)
3 1 “I am about to send my messenger, who will clear the way before me. Indeed, the Lord you are seeking will suddenly come to his temple, and the messenger of the covenant, whom you long for, is certainly coming,” says the Lord who rules over all.
2 Who can endure the day of his coming? Who can keep standing when he appears? For he will be like a refiner’s fire, like a launderer’s soap. 3 He will act like a refiner and purifier of silver and will cleanse the Levites and refine them like gold and silver. Then they will offer the Lord a proper offering.
