The book of Acts records that an Alexandrian Jew named Apollos was active as a missionary in Ephesus and Achaia (18:24–28). Although skillful in communicating and knowledgeable concerning scripture, his teaching on baptism was incomplete. Priscilla and Aquila needed to provide him with a “more accurate” understanding, and when Paul visited Ephesus after Apollos's departure (Acts 19.1–7), he had to rebaptize some people who had known John's baptism for repentance but not baptism in the name of Jesus.

In 1 Corinthians, Paul's references to Apollos and his teachings betray some tension between the two leaders (1 Cor 1.12; 3.4–6; 4.6; 16.12).
