Who Was Baptized Twice In The Bible

"While Apollos was at Corinth, Paul took the road through the interior and arrived at Ephesus. There he found some disciples and asked them, "Did you receive the Holy Spirit when you believed?" They answered, "No, we have not even heard that there is a Holy Spirit." So Paul asked, "Then what baptism did you receive?" "John's baptism," they replied. Paul said, "John's baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus." Hearing this, they were baptized in the name of the Lord Jesus. When Paul placed his hands on them, the Holy Spirit came on them, and they spoke in tongues and prophesied. There were about twelve men in all." -Acts 19:1-6

Acts 19:1-6 mentions that twelve disciples of Paul received baptism twice, one a baptism of repentance from Jesus's cousin John the Baptist, and the other a baptism in the name of Jesus Christ. The latter was a real baptism since the holy spirit blessed them. The Holy Spirit is believed to confer the gift of understanding, so they spoke in different languages and were able to make prophecies.
