<p>8:23 <i>Whether any inquire about Titus, he is my partner and my fellow-worker toward you; or our brothers, they are the messengers of the churches, they are the glory of Christ</i>- The Corinthians knew Titus, for he had already visited them. So this 'enquiry' would not be in the sense that they didn't know who he was. It was Titus who had visited them and 'begun' the project with them, and he had just returned to Paul from a visit to Corinth (7:13). And Paul was now sending him to them again in the hope they would give him the promised donations. So the 'enquiry' was rather of another kind, reflecting a hostility towards Titus and the brothers with him. This reveals that Paul's claim about the mutual love between Titus and the Corinthians was again an emotional exaggeration, and he had to as it were come down to earth and in reality defend Titus against the scepticism the Corinthians had about him.&nbsp;</p>
