The fining pot is for silver, and the furnace for gold: but the LORD trieth the hearts.
As silver is melted in the midst of the furnace, so shall ye be melted in the midst thereof; and ye shall know that I the LORD have poured out my fury upon you.
And he shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness.
