Where did Paul go after missing Titus at Troas, and what condition was he in there?
After missing Titus at Troas, Paul went on to Philippi in northern Greece, where he was evidently on his sickbed near death, almost despairing of life because of tremendous sickness. After recovering, he later made his way down and visited Corinth a second time.
Les explains that Paul missed Titus meeting him at Troas, so he went on up to Philippi in northern Greece. There he was evidently on his sickbed nigh unto death, and this became the backdrop for the next few verses, when he was almost despairing of his life because of his tremendous sickness. In time, after he got well, he made his way down and finally visited Corinth a second time. Les also connects this to 2 Corinthians 4:7, where Paul speaks of having this treasure in earthen vessels, meaning the body of flesh made up of the elements of the earth, not a clay pot.
