Acts 19:2-6

He asked them, “Did you receive the Holy Spirit when you believed [in Jesus as the Christ]?” And they said, “No, we have not even heard that there is a Holy Spirit.” And he asked, “Into what then were you baptized?” They said, “Into John’s baptism.” Paul said, “John performed a baptism of repentance, continually telling the people to believe in Him who was coming after him, that is, [to confidently accept and joyfully believe] in Jesus [the Messiah and Savior].” After hearing this, they were baptized [again, this time] in the name of the Lord Jesus. And when Paul laid his hands on them, the Holy Spirit came on them, and they began speaking in [unknown] tongues (languages) and prophesying.
