2 Corinthians 8:16

One of Paul’s representatives, whom he was sending to Corinth to pick up their gift, was Titus. His readers had met him, received ministry from him, and would see him again shortly. Paul again affirmed Titus’ love for the Corinthians so they would receive him happily. The apostle also expressed thanks to God for working in Titus to give him his good attitude. Titus, as Paul, felt concern for the Corinthians personally, not just for their money (cf. 2 Corinthians 12:14).

"The Corinthians might think that the zeal of Titus for the relief-fund was zeal on behalf of the Jerusalem poor; but it was really on behalf of the Corinthians. They would be the chief losers if a suitable sum was not raised in Corinth." [Note: Plummer, p. 247.]
