Acts 19:1-3

1It happened that while Apollos was in Corinth, Paul went through the upper [inland] districts and came down to Ephesus, and found some disciples.

2He asked them, “Did you receive the Holy Spirit when you believed [in Jesus as the Christ]?” And they said, “No, we have not even heard that there is a Holy Spirit.”

3And he asked, “Into what then were you baptized?” They said, “Into John’s baptism.”
