1 Timothy 1:18-20
18 Timothy, my son, I am giving you this instruction in keeping with the prophecies previously made about you, so that by them you may strongly engage in battle, 19 having faith and a good conscience. Some have rejected these and have suffered the shipwreck of their faith. 20 Hymenaeus and Alexander are among them, and I have delivered them to Satan, so that they may be taught not to blaspheme.
2 Timothy 4:1-8
1 I solemnly charge you before God and Christ Jesus, who is going to judge the living and the dead, and because of His appearing and His kingdom: 2 Proclaim the message; persist in it whether convenient or not; rebuke, correct, and encourage with great patience and teaching. 3 For the time will come when they will not tolerate sound doctrine, but according to their own desires, will multiply teachers for themselves because they have an itch to hear something new. 4 They will turn away from hearing the truth and will turn aside to myths. 5 But as for you, be serious about everything, endure hardship, do the work of an evangelist, fulfill your ministry.
6 For I am already being poured out as a drink offering, and the time for my departure is close. 7 I have fought the good fight, I have finished the race, I have kept the faith. 8 There is reserved for me in the future the crown of righteousness, which the Lord, the righteous Judge, will give me on that day, and not only to me, but to all those who have loved His appearing.
