1 Timothy 1:18-20
18 This command I entrust to you, Timothy, my son, in accordance with the prophecies previously made concerning you, that by them you fight the good fight, 19 keeping faith and a good conscience, which some have rejected and suffered shipwreck in regard to their faith. 20 Among these are Hymenaeus and Alexander, whom I have handed over to Satan, so that they will be taught not to blaspheme.
