Acts 18:18-26

Paul stayed for a while longer, and then told the brothers and sisters goodbye and sailed for Syria; and he was accompanied by Priscilla and Aquila. At Cenchrea [the southeastern port of Corinth] he had his hair cut, because he was keeping a [Nazirite] vow [of abstention]. Then they arrived in Ephesus, and he left the others there; but he entered the synagogue and reasoned and debated with the Jews. When they asked him to stay for a longer time, he refused; but after telling them goodbye and saying, “I will return again if God is willing,” he set sail from Ephesus. When he had landed at Caesarea, he went up and greeted the church [at Jerusalem], and then went down to Antioch. After spending some time there, he left and traveled through the territory of Galatia and Phrygia, strengthening and encouraging all the disciples. Now a Jew named Apollos, a native of Alexandria, came to Ephesus. He was an eloquent and cultured man, and well versed in the [Hebrew] Scriptures. This man had been instructed in the way of the Lord, and being spiritually impassioned, he was speaking and teaching accurately the things about Jesus, though he knew only the baptism of John; and he began to speak boldly and fearlessly in the synagogue. But when Priscilla and Aquila heard him, they took him aside and explained more accurately to him the way of God [and the full story of the life of Christ].
