You too should beware of him, for he has vigorously opposed our message.
Timothy must beware of Alexander as well, because he strongly opposed their message.
It turns Paul's experience into protective counsel for Timothy.
9Make every effort to come to me quickly, 10because Demas, in his love of this world, has deserted me and gone to Thessalonica. Crescens has gone to Galatia, and Titus to Dalmatia. 11Only Luke is with me. Get Mark and bring him with you, because he is useful to me in the ministry. 12Tychicus, however, I have sent to Ephesus. 13When you come, bring the cloak that I left with Carpus at Troas, and my scrolls, especially the parchments. 14Alexander the coppersmith did great harm to me. The Lord will repay him according to his deeds. 15You too should beware of him, for he has vigorously opposed our message.
