1 Timothy 1:18-20 NIV

[18] Timothy, my son, I am giving you this command in keeping with the prophecies once made about you, so that by recalling them you may fight the battle well, [19] holding on to faith and a good conscience, which some have rejected and so have suffered shipwreck with regard to the faith. [20] Among them are Hymenaeus and Alexander, whom I have handed over to Satan to be taught not to blaspheme.
