Where was Paul when Titus was at Corinth, and what report did Titus bring back?

Paul was at Ephesus while Titus was at Corinth. Titus returned with a positive report: the Corinthians were speaking good things about Paul, still loved him, and held him in high esteem. This greatly encouraged Paul, showing his humanity and desire for affirmation after the severe letter.

Les explains that Titus had been down at Corinth, while Paul was over at Ephesus. Paul had written that letter to the Corinthians and had to dress them down severely. He had heard things from the Corinthian congregation that were against him and condemning him. But then Titus came back with nothing but good things the Corinthians were saying about Paul. This showed how human Paul was. He was tickled to death to see Titus, but what thrilled him more was the report that the Corinthian people still loved him and still held him in high esteem, so he rejoiced all the more. This came even though he had made them sorry with a letter.
