Isaiah 1:25; Ezekiel 22:18; Malachi 3:2-3

25  zI will turn my hand against you

and will smelt away your adross as with lye

and remove all your alloy.


18 fSon of man, the house of Israel has become gdross to me; all of them are hbronze and tin and iron and lead in the furnace; they are idross of silver.


But lwho can endure the day of his coming, and who can stand when he appears? For mhe is like a refiner's fire and like fullers' soap. He will sit nas a refiner and purifier of silver, and he will purify the sons of Levi and refine them like gold and silver, and they will bring oofferings in righteousness to the Lord.1
