And I will turn my hand upon thee, and purely purge away thy dross, and take away all thy tin:
Behold, I have refined thee, but not with silver; I have chosen thee in the furnace of affliction.
Therefore thus saith the LORD of hosts, Behold, I will melt them, and try them; for how shall I do for the daughter of my people?
And I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: they shall call on my name, and I will hear them: I will say, It is my people: and they shall say, The LORD is my God.
But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner's fire, and like fullers' soap: 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.
As for God, his way is perfect: the word of the LORD is tried: he is a buckler to all those that trust in him.
