Acts 18: 9 - 18
9 And the Lord said to Paul one night in a vision, "Do not be afraid, but speak and do not be silent;
10 for I am with you, and no man shall attack you to harm you; for I have many people in this city."
11 And he stayed a year and six months, teaching the word of God among them.
12 But when Gallio was proconsul of Acha'ia, the Jews made a united attack upon Paul and brought him before the tribunal,
13 saying, "This man is persuading men to worship God contrary to the law."
14 But when Paul was about to open his mouth, Gallio said to the Jews, "If it were a matter of wrongdoing or vicious crime, I should have reason to bear with you, O Jews;
15 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."
16 And he drove them from the tribunal.
17 And they all seized Sos'thenes, the ruler of the synagogue, and beat him in front of the tribunal. But Gallio paid no attention to this.
18 After this Paul stayed many days longer, and then took leave of the brethren and sailed for Syria, and with him Priscilla and Aq'uila. At Cen'chre-ae he cut his hair, for he had a vow.
