1 Timothy 1:18-20 NRS

18 I am giving you these instructions, Timothy, my child, in accordance with the prophecies made earlier about you, so that by following them you may fight the good fight,
19 having faith and a good conscience. By rejecting conscience, certain persons have suffered shipwreck in the faith;
20 among them are Hymenaeus and Alexander, whom I have turned over to Satan, so that they may learn not to blaspheme.
