Some of the wise will fall so that they may be refined, purified, and made spotless until the time of the end, for it will still come at the appointed time.
KJV
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.
ASV
And some of them that are wise shall fall, to refine them, and to purify, and to make them white, even to the time of the end; because it is yet for the time appointed.
