1 Timothy 1:18-20

18This charge I entrust to you, Timothy, my child, in accordance with the prophecies previously made about you, that by them you may wage the good warfare,

19holding faith and a good conscience. By rejecting this, some have made shipwreck of their faith,

20among whom are Hymenaeus and Alexander, whom I have handed over to Satan that they may learn not to blaspheme.
