Bible Verses About Silver: Purified by fire

The refining pot is for silver, and the furnace for gold; But Jehovah trieth the hearts.

And I will bring the third part into 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, Jehovah is my God.
