2But who can endure the day of His coming? And who can stand when He appears? For He will be like a refiner’s fire, like a launderer’s soap.
3And He will sit as a refiner and purifier of silver; He will purify the sons of Levi and refine them like gold and silver. Then they will present offerings to the LORD in righteousness.
4Then the offerings of Judah and Jerusalem will please the LORD, as in days of old and years gone by.
5“Then I will draw near to you for judgment. And I will be a swift witness against sorcerers and adulterers and perjurers, against oppressors of the widowed and fatherless, and against those who defraud laborers of their wages and deny justice to the foreigner but do not fear Me,” says the LORD of Hosts.
