1 Timothy 1:18-20 RSV

18 This charge I commit to you, Timothy, my son, in accordance with the prophetic utterances which pointed to you, that inspired by them you may wage the good warfare,
19 holding faith and a good conscience. By rejecting conscience, certain persons have made shipwreck of their faith,
20 among them Hymenae'us and Alexander, whom I have delivered to Satan that they may learn not to blaspheme.
