To emphasize the purification process needed for the coming Messiah, Malachi used two images: a refiner's fire and what other cleaning agent?
Answer Launderer's soap
A launderer's soap in Bible times was lye, a highly aggressive and harsh substance used to scrub stains out. Refinement would occur by fire and a launderer's soap would occur with water. All of it to make us purified to stand before God.
