Malachi 3:2-4

Complete Jewish Bible

² But who can endure the day when he comes?
Who can stand when he appears?
For he will be like a refiner’s fire,
like the soapmaker’s lye.
³ He will sit, testing and purifying the silver;
he will purify the sons of Levi,
refining them like gold and silver,
so that they can bring offerings to Adonai uprightly.
⁴ Then the offering of Y’hudah and Yerushalayim
will be pleasing to Adonai,
as it was in the days of old,
as in years gone by.
