Note 3 at 2 Cor. 2:13: Paul had evidently arranged to meet Titus at Troas. As time passed with no news from Titus, Paul became restless in spirit. The term "no rest in my spirit" suggests that Paul could not relax or be at ease so he said farewell to the church at Troas and pressed on into Macedonia.

Note 4 at 2 Cor. 2:13: Titus is mentioned by name 13 times in 12 verses of scripture (here; 2 Cor. 7:6, 13, 14; 2 Cor. 8:6, 16, 23; 2 Cor. 12:18; Gal. 2:1, 3; 2 Tim. 4:10; Ti. 1:4). He is also mentioned in the subscripts which are included in some Bibles at the end of 2 Corinthians and Titus. From the subscript at the end of the book of Titus we find that Titus was ordained the first bishop of the Cretians, which was basically stated by Paul in Titus 1:5. Titus was not mentioned by name in the book of Acts, although it is evident by Paul's statements that he was Paul's companion in travel.

From Galatians 2:1 we learn that Titus was a companion of Paul when Paul was sent to Jerusalem to resolve the dispute over circumcision (see note 2 at Acts 15:1, p. 659). In Galatians 2:3, Paul states that Titus was a Greek who had been converted to Christianity, apparently under Paul's ministry (Ti. 1:4). Paul mentions this because of the legalistic Jews who secretly spied on Paul's companions to see if they were circumcised (Gal. 2:4-5). For this very reason, Paul makes special mention that he did not circumcise Titus.

From Paul's statement in 2 Corinthians 7:14, it appears Titus was not with Paul during his first visit to Corinth but was sent to them as Paul's special envoy prior to his second visit (2 Cor. 12:17-18). Titus' assignment was to minister to the Corinthians about their collection for the poor saints at Jerusalem (2 Cor. 8:6; Rom. 15:26). Titus also brought Paul word about how the Corinthians had received Paul's rebukes and instructions in the epistle we call First Corinthians (2 Cor. 7:6-11).

Paul said Titus was his partner and fellowhelper to the Corinthians (2 Cor. 8:23). Titus didn't just minister to the Corinthians as a duty, but Paul reveals that God put a real love in Titus' heart for the Corinthians (2 Cor. 8:16-17) and Titus had great joy and was refreshed by the way the Corinthians received him (2 Cor. 7:13-15).

This verse (v. 13) is describing an arranged meeting, which failed to happen, between Paul and Titus as Titus was returning from Corinth. Paul had no rest in his spirit because he was anxious to hear about the Corinthians from Titus. He did meet up with Titus sometime after his departure from Troas and received the good reports from Titus about how the Corinthian church had submitted to Paul's instructions (2 Cor. 7:6-13).

Titus was with Paul during Paul's voyage to Rome because Ti. 1:5 says, "For this cause left I thee in Crete, that thou shouldest set in order the things that are wanting, and ordain elders in every city, as I had appointed thee." The only time scripture records Paul being in Crete was as a prisoner on his way to Rome (Acts 27:7-8). Therefore, Titus must have been one of those in Paul's company mentioned in Acts 21:8.
