While Apollos was in Corinth, Paul went through the inland regions and came to Ephesus. He found some disciples there and said to them, “Did you receive the Holy Spirit when you believed?” They replied, “No, we have not even heard that there is a Holy Spirit.” So Paul said, “Into what then were you baptized?” “Into John’s baptism,” they replied. Paul said, “John baptized with a baptism of repentance, telling the people to believe in the one who was to come after him, that is, in Jesus.” When they heard this, they were baptized in the name of the Lord Jesus, and when Paul placed his hands on them, the Holy Spirit came upon them, and they began to speak in tongues and to prophesy. (Now there were about twelve men in all.)
So Paul entered the synagogue and spoke out fearlessly for three months, addressing and convincing them about the kingdom of God.
