1 Timothy 1:18-20

18 I betake this commandment to thee, thou son Timothy, after the prophecies that have been heretofore in thee, that thou travail [or fight] in them a good travail,

19 having faith and good conscience, which some men cast away, and perished about the faith.

20 Of which is Hymenaeus and Alexander, whom I betook to Satan, that they learn not to blaspheme.
