Bible Verses About Silver: Purified by fire

As silver is tried by fire, and gold in the furnace: so the Lord trieth the hearts.

And I will bring the third part through the fire, and will refine them as silver is refined: and I will try them as gold is tried. They shall call on my name, and I will hear them. I will say: Thou art my people: and they shall say: The Lord is my God.
