Luke’s narrative was compressed in the previous paragraph because he wants to get Paul to Ephesus. So, Luke takes us now to Ephesus and he begins with Apollos:
18:24 Now a Jew named Apollos, a native of Alexandria, arrived in Ephesus. He was an eloquent speaker, well-versed in the scriptures. 18:25 He had been instructed in the way of the Lord, and with great enthusiasm he spoke and taught accurately the facts about Jesus, although he knew only the baptism of John. 18:26 He began to speak out fearlessly in the synagogue, but when Priscilla and Aquila heard him, they took him aside and explained the way of God to him more accurately. 18:27 When Apollos wanted to cross over to Achaia, the brothers encouraged him and wrote to the disciples to welcome him. When he arrived, he assisted greatly those who had believed by grace, 18:28 for he refuted the Jews vigorously in public debate, demonstrating from the scriptures that the Christ was Jesus.
