Isaiah 1:25

³and he will sit as a refiner and purifier of silver, and he will purify the sons of Levi, and refine them as gold and silver; and they shall offer to the LORD offerings in righteousness.

²²Your silver has become dross, your wine mixed with water.

⁴when the Lord shall have washed away the filth of the daughters of Zion, and shall have purged the blood of Jerusalem from within it, by the spirit of justice and by the spirit of burning.

⁷Therefore the LORD of Armies says, “Behold, I will melt them and test them; for how should I deal with the daughter of my people?

²⁹The bellows blow fiercely. The lead is consumed in the fire. In vain they go on refining, for the wicked are not plucked away.

²²As silver is melted in the middle of the furnace, so you will be melted in the middle of it; and you will know that I, the LORD, have poured out my wrath on you.’”

¹¹In that day you will not be disappointed for all your doings in which you have transgressed against me; for then I will take away out from among you your proudly exulting ones, and you will no more be arrogant in my holy mountain.

¹¹Then I said, “Lord, how long?” He answered, “Until cities are waste without inhabitant, houses without man, the land becomes utterly waste,

¹²and the LORD has removed men far away, and the forsaken places are many within the land. ¹³If there is a tenth left in it, that also will in turn be consumed, as a terebinth, and as an oak whose stump remains when they are cut down, so the holy seed is its stump.”

³⁸I will purge out from among you the rebels and those who disobey me. I will bring them out of the land where they live, but they shall not enter into the land of Israel. Then you will know that I am the LORD.”

²⁰As they gather silver, bronze, iron, lead, and tin into the middle of the furnace, to blow the fire on it, to melt it, so I will gather you in my anger and in my wrath, and I will lay you there and melt you.
