Acts 19:1-7
19:1 While Apollos was in Corinth, Paul passed through the interior regions and came to Ephesus, where he found some disciples.
19:2 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."
19:4 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."
19:5 On hearing this, they were baptized in the name of the Lord Jesus.
19:6 When Paul had laid his hands on them, the Holy Spirit came upon them, and they spoke in tongues and prophesied--
9:7 altogether there were about twelve of them.
