Acts 19:3-5

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.
