Daniel 11:32-35

With flattery he will corrupt those who act wickedly toward the covenant, but the people who know their God will be strong and take action. Those who have insight among the people will give understanding to many, yet they will fall by the sword and flame, and they will be captured and plundered for a time. When they fall, they will be helped by some, but many others will join them insincerely. Some of those who have insight will fall so that they may be refined, purified, and cleansed until the time of the end, for it will still come at the appointed time.
