Daniel 11:33-35

“Wise leaders will give instruction to many, but these teachers will die by fire and sword, or they will be jailed and robbed. During these persecutions, little help will arrive, and many who join them will not be sincere. And some of the wise will fall victim to persecution. In this way, they will be refined and cleansed and made pure until the time of the end, for the appointed time is still to come.
