1 Timothy 1:18-20

18This charge I commit unto thee, my child Timothy, according to the prophecies which led the way to thee, that by them thou mayest war the good warfare; 19holding faith and a good conscience; which some having thrust from them made shipwreck concerning the faith: 20of whom is Hymenæus and Alexander; whom I delivered unto Satan, that they might be taught not to blaspheme.
