Malachi 3:1-3

“Behold, I send My messenger, And he will prepare the way before Me. And the Lord, whom you seek, Will suddenly come to His temple, Even the Messenger of the covenant, In whom you delight. Behold, He is coming,” Says the LORD of hosts. “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 launderers’ soap. He will sit as a refiner and a purifier of silver; He will purify the sons of Levi, And purge them as gold and silver, That they may offer to the LORD An offering in righteousness.
