Isaiah 48:10

Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:

The fining pot is for silver, and the furnace for gold: but the Lord trieth the hearts.

But he knoweth the way that I take: when he hath tried me, I shall come forth as gold.

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

For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness. Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.

That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:

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?

But the Lord hath taken you, and brought you forth out of the iron furnace, even out of Egypt, to be unto him a people of inheritance, as ye are this day.

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 many as I love, I rebuke and chasten: be zealous therefore, and repent.

And it shall come to pass, that in all the land, saith the Lord, two parts therein shall be cut off and die; but the third shall be left therein. 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.

Son of man, the house of Israel is to me become dross: all they are brass, and tin, and iron, and lead, in the midst of the furnace; they are even the dross of silver. Therefore thus saith the Lord God; Because ye are all become dross, behold, therefore I will gather you into the midst of Jerusalem. As they gather silver, and brass, and iron, and lead, and tin, into the midst of the furnace, to blow the fire upon it, to melt it; so will I gather you in mine anger and in my fury, and I will leave you there, and melt you. Yea, I will gather you, and blow upon you in the fire of my wrath, and ye shall be melted in the midst thereof. As silver is melted in the midst of the furnace, so shall ye be melted in the midst thereof; and ye shall know that I the Lord have poured out my fury upon you.

For they be thy people, and thine inheritance, which thou broughtest forth out of Egypt, from the midst of the furnace of iron:

And I will purge out from among you the rebels, and them that transgress against me: I will bring them forth out of the country where they sojourn, and they shall not enter into the land of Israel: and ye shall know that I am the Lord.

And I will turn my hand upon thee, and purely purge away thy dross, and take away all thy tin: And I will restore thy judges as at the first, and thy counsellors as at the beginning: afterward thou shalt be called, The city of righteousness, the faithful city.
