“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.
