Daniel 11:33-35 NIV

[33] “Those who are wise will instruct many, though for a time they will fall by the sword or be burned or captured or plundered. [34] When they fall, they will receive a little help, and many who are not sincere will join them. [35] Some of the wise will stumble, 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.
