Acts 19:1 – 7 New International Version (NIV)
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[a] 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.
4 Paul said, “John’s baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus.” 5 On hearing this, they were baptized in the name of the Lord Jesus.
6 When Paul placed his hands on them, the Holy Spirit came on them, and they spoke in tongues[b] and prophesied. 7 There were about twelve men in all.
