Acts 19:1-3

Now it happened that while Apollos was in Corinth, Paul passed through the upper country and came to Ephesus, and found some disciples.

He said to them, “Did you receive the Holy Spirit when you believed?” And they said to him, “On the contrary, we have not even heard if there is a Holy Spirit.”

And he said, “Into what then were you baptized?” And they said, “Into John’s baptism.”
