Albert Barnes Commentary Acts 19:1

"And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper country came to Ephesus, and found certain disciples:" — Acts 19:1 (ASV)

CHAPTER 19

While Apollos was at Corinth. It is probable that he remained there a considerable time.

Paul having passed through the upper coasts. The upper, or more elevated regions of Asia Minor. The writer refers here particularly to the provinces of Phrygia and Galatia, Acts 18:23. These regions were called upper, because they were situated on the high table-land in the interior of Asia Minor; while Ephesus was in the low maritime regions, and called the low country.

Came to Ephesus. Agreeably to his promise, Acts 18:21.

And finding certain disciples. Certain persons who had been baptized into John's baptism, and who had embraced John's doctrine, that the Messiah was soon to appear, Acts 19:3–4. It is very clear that they had not yet heard that he had come, or that the Holy Ghost was given. They were evidently in the same situation as Apollos. See Barnes' notes on Acts 18:25.
