⁶ The words of the Lord are pure words: as silver tried in a furnace of earth, purified seven times.

¹⁰ For thou, O God, hast proved us: thou hast tried us, as silver is tried.

⁷ 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?

³⁵ And some of them of understanding shall fall, to try them, and to purge, and to make them white, even to the time of the end: because it is yet for a time appointed.

³ 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.
