Malachi 3:1-2

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.

3:2 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.
