Daniel 11:32-35

Those who do wickedly against the covenant he shall corrupt with flattery; but the people who know their God shall be strong, and carry out great exploits. And those of the people who understand shall instruct many; yet for many days they shall fall by sword and flame, by captivity and plundering. Now when they fall, they shall be aided with a little help; but many shall join with them by intrigue. And some of those of understanding shall fall, to refine them, purify them, and make them white, until the time of the end; because it is still for the appointed time.
