Acts 19:1-3 NIV

[1] While Apollos was at Corinth, Paul took the road through the interior and arrived at Ephesus. There he found some disciples [2] and asked them, “Did you receive the Holy Spirit when you believed?” They answered, “No, we have not even heard that there is a Holy Spirit.” [3] So Paul asked, “Then what baptism did you receive?” “John’s baptism,” they replied.
