Acts 19:1-7 NRSV
While Apollos was in Corinth, Paul passed through the interior regions and came to Ephesus, where he found some disciples. He said to them, “Did you receive the Holy Spirit when you became believers?” They replied, “No, we have not even heard that there is a Holy Spirit.” Then he said, “Into what then were you baptized?” They answered, “Into John's baptism.” Paul said, “John baptized with the baptism of repentance, telling the people to believe in the one who was to come after him, that is, in Jesus.” On hearing this, they were baptized in the name of the Lord Jesus. When Paul had laid his hands on them, the Holy Spirit came upon them, and they spoke in tongues and prophesied— altogether there were about twelve of them.
