Malachi 3:2-3

Amplified Bible

² 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 launderer’s soap [which removes impurities and uncleanness].^{(A) 3} He will sit as a refiner and purifier of silver, and He will purify the sons of Levi [the priests], and refine them like gold and silver, so that they may present to the Lord [grain] offerings in righteousness.
