Acts of the Apostles 19:1-3

While Apollos was in Corinth, Paul traveled through the interior regions until he reached Ephesus, on the coast, where he found several believers. “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.” “Then what baptism did you experience?” he asked. And they replied, “The baptism of John.”
