1 Timothy 1:18-20 YLT

18 This charge I commit to thee, child Timotheus, according to the prophesies that went before upon thee, that thou mayest war in them the good warfare,
19 having faith and a good conscience, which certain having thrust away, concerning the faith did make shipwreck,
20 of whom are Hymenaeus and Alexander, whom I did deliver to the Adversary, that they might be instructed not to speak evil.
