Paul’s Third Missionary Journey
1 While Apollos was in Corinth, Paul traveled through the interior regions until he reached Ephesus, on the coast, where he found several believers.19:1 Greek disciples; also in 19:9, 30.2 "Did you receive the Holy Spirit when you believed?" he asked them.
"No," they replied, "we haven’t even heard that there is a Holy Spirit."
3 "Then what baptism did you experience?" he asked.
And they replied, "The baptism of John."
