Thematic Bible: The lord refining

Awake! O sword, against the keeper of my flock, and against him who is with me, says the Lord of armies: put to death the keeper of the sheep, and the sheep will go in flight: and my hand will be turned against the little ones. And it will come about that in all the land, says the Lord, two parts of it will be cut off and come to an end; but the third will be still living there. And I will make the third part go through the fire, cleaning them as silver is made clean, and testing them as gold is tested: and they will make their prayer to me and I will give them an answer: I will say, It is my people; and they will say, The Lord is my God.

See, I am sending my servant, and he will make ready the way before me; and the Lord, whom you are looking for, will suddenly come to his Temple; and the angel of the agreement, in whom you have delight, see, he is coming, says the Lord of armies. But by whom may the day of his coming be faced? and who may keep his place when he is seen? for he is like the metal-tester's fire and the cleaner's soap. He will take his seat, testing and cleaning the sons of Levi, burning away the evil from them as from gold and silver; so that they may make offerings to the Lord in righteousness.
