While Apollos was in Corinth, Paul took the inland route and arrived in Ephesus where he found some believers. “Did you receive the Holy Spirit when you believed?” he asked them.
“No, we haven't heard anything about a Holy Spirit,” they told him.
“So what baptism did you receive?” he asked.
“John's baptism,” they replied.
“John baptized with the baptism of repentance,” said Paul. He told the people that they should trust in the one who would come after him—that is, they should trust in Jesus. When they heard this, they were baptized in the name of the Lord Jesus. After Paul had placed his hands on them, the Holy Spirit came upon them and they spoke in tongues and prophesied. There were about twelve of them in total.
Paul went to the synagogue and over the course of the next three months spoke boldly to those who were there, discussing with them and trying to convince them about the kingdom of God.
