<p>4:21 <i>Try by all means- </i>At the bitter end, the way Paul begs nervous, spiritually and physically weak Timothy to try to get to him before he dies has something pathetic about it: &quot;Do thy diligence to come... do thy diligence to come&quot;, he repeats twice over (2 Tim. 4:9,21 AV). The spiritual weakness of Timothy and his need for Paul's encouragement is quite a theme (1 Cor. 16:10; 1 Tim. 4:12,14; 2 Tim. 1:6-8; 4:2).</p><p><i>To come before winter- </i>The urgency may be because without the cloak he would have frozen in his cell (:13). But he knows that the time of his departure is near. He knows that travelling to Rome by sea in Winter is dangerous- as he had experienced. So he wished Timothy to come immediately and not miss the shipping season.</p><p><i>Eubulus greets you, and Pudens and Linus and Claudia, and all the brothers</i>- We note his grace in passing on these greetings; because these would have been amongst those who sadly did not stand with Paul in support at his trial (:16).</p>
