Acts 18:12-21 ESV
But when Gallio was proconsul of Achaia, the Jews made a united attack on Paul and brought him before the tribunal, saying, “This man is persuading people to worship God contrary to the law.” But when Paul was about to open his mouth, Gallio said to the Jews, “If it were a matter of wrongdoing or vicious crime, O Jews, I would have reason to accept your complaint. But since it is a matter of questions about words and names and your own law, see to it yourselves. I refuse to be a judge of these things.” And he drove them from the tribunal. And they all seized Sosthenes, the ruler of the synagogue, and beat him in front of the tribunal. But Gallio paid no attention to any of this.
After this, Paul stayed many days longer and then took leave of the brothers and set sail for Syria, and with him Priscilla and Aquila. At Cenchreae he had cut his hair, for he was under a vow. And they came to Ephesus, and he left them there, but he himself went into the synagogue and reasoned with the Jews. When they asked him to stay for a longer period, he declined. But on taking leave of them he said, “I will return to you if God wills,” and he set sail from Ephesus.
