Daniel 12:10

“And some of those who have insight will fall, in order to refine, purge, and make them pure until the time of the end, because it is still to come at the appointed time.

“And those who have insight will shine brightly like the brightness of the expanse of heaven, and those who lead the many to righteousness, like the stars forever and ever.

“And He will sit as a smelter and purifier of silver, and He will purify the sons of Levi and refine them like gold and silver, so that they may present to Yahweh offerings in righteousness.

“If anyone is willing to do His will, he will know about the teaching, whether it is of God or I speak from Myself.

“Let the one who does unrighteousness, still do unrighteousness; and the one who is filthy, still be filthy; and let the one who is righteous, still do righteousness; and the one who is holy, still keep himself holy.”
