Note 1 at Ac 18:22: This ended Paul's second missionary trip. On this second missionary journey, Paul had chosen Silas as his companion instead of Barnabas (Ac 15:39-40). He had then retraced his steps back through Asia (see note 3 at Ac 16:6), visiting the places where he had ministered on his first trip (Ac 15:41-16:6). In Derbe (see note 5 at Ac 14:6) or Lystra (see note 4 at Ac 14:6), Paul had taken Timotheus (see note 1 at Ac 16:1) to travel with him as a coworker.

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

On Paul's second missionary trip, he basically covered all the places he had visited on his first trip (see note 2 at Ac 14:26) plus an additional 2,000 miles, at least, as he traveled through Macedonia (see note 1 at Ac 16:9) and Greece, to Jerusalem (see note 1 at Joh 5:1), and back to Antioch (see note 3 at Ac 11:19). That would bring the total distance traveled on this trip to over 3,200 miles.

The dates of this second missionary trip are about A.D. 51 to 53. This can be deduced from the fact that secular history has dated Claudius Caesar's order for the Jews to leave Rome as either A.D. 49 or 50 (see note 1 at Ac 18:1). Ac 18:2 says that Aquila 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 1,300-plus miles to Corinth and minister along the way.

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