Note 1 at Acts 18:22: This ends Paul's second missionary trip. On this second missionary journey, Paul chose Silas as his companion instead of Barnabas (Acts 15:40). He then retraced his steps back through Asia (see note 3 at Acts 16:6, p. 665), visiting the places he had ministered on his first trip (Acts 15:41-16:6). In Derbe (see note 5 at Acts 14:6, p. 656) or Lystra (see note 4 At Acts 14:6, p. 655), Paul took Timotheus (see note 1 at Acts 16:1, p. 665) to travel with him as a co-worker.

Paul had a vision that brought him to Philippi (Acts 16:9-12) and the first European converts were made (Acts 16:14-15, 33-34). In a Philippian prison, Paul and Silas had their cells opened and their chains broken by an earthquake (Acts 16:26). Paul went on to minister in Thessalonica (see note 3 at Acts 17:1, p. ???), Berea (see note 1 at Acts 17:10, p. ???), Athens (see note 1 at Acts 17:15, p. ???), Corinth (see note 1 at Acts 18:1, p. ???), and Ephesus (see note 3 at Acts 18:19, p. ???) before going to Jerusalem and finally back to Antioch (see note 3 at Acts 11:19, p. 638).

On Paul's third missionary trip, he basically covered all the places he had visited on his first trip (see note 2 at Acts 14:26, p. 658) plus an additional 2000 miles at least as he traveled through Macedonia (see note 1 at Acts 16:9, p. 667), Greece, to Jerusalem (see note 1 at Jn. 5:1, p. 150) and back to Antioch (see note 3 at Acts 11:19, p. 638). That would bring the total distance traveled on this trip to over 3,200 miles.

The dates of this second missionary trip are about 51-53 A.D.. This can be deduced from the fact that secular history has dated Claudius Caesar's order for the Jews to leave Rome at 52 A.D. (see note 1 at Acts 18:1, p. ???). Acts 18:2 says that Aquilla and Priscilla had just recently come from Rome because of this order and Paul arrived in Corinth about that same time. Although the scriptures don't give the details of how long it took Paul to reach Corinth, it can be supposed that at least the better part of a year was used to travel the 1300+ miles to Corinth and minister along the way.

History also records Gallio (see note 10 at Acts 18:12, p. ???) as being the deputy of Achaia (see note 11 at Acts 18:12, p. ???) from 51-53 A.D. thereby confirming the date that Paul must have been in Corinth (Acts 18:12). We know that Paul stayed in Corinth at least 18 months (Acts 18:11, 18) and then hurried to Jerusalem (Acts 18:21).
