4 Each Sabbath found Paul at the synagogue, trying to convince the Jews and Greeks alike. 5 And after Silas and Timothy came down from Macedonia, Paul spent all his time preaching the word. He testified to the Jews that Jesus was the Messiah. 6 But when they opposed and insulted him, Paul shook the dust from his clothes and said, "Your blood is upon your own heads-I am innocent. From now on I will go preach to the Gentiles."
7 Then he left and went to the home of Titius Justus, a Gentile who worshiped God and lived next door to the synagogue. 8 Crispus, the leader of the synagogue, and everyone in his household believed in the Lord. Many others in Corinth also heard Paul, became believers, and were baptized. 9 One night the Lord spoke to Paul in a vision and told him, "Don't be afraid! Speak out! Don't be silent! 10 For I am with you, and no one will attack and harm you, for many people in this city belong to me." 11 So Paul stayed there for the next year and a half, teaching the word of God.
12 But when Gallio became governor of Achaia, some Jews rose up together against Paul and brought him before the governor for judgment. 13 They accused Paul of "persuading people to worship God in ways that are contrary to our law." 14 But just as Paul started to make his defense, Gallio turned to Paul's accusers and said, "Listen, you Jews, if this were a case involving some wrongdoing or a serious crime, I would have a reason to accept your case. 15 But since it is merely a question of words and names and your Jewish law, take care of it yourselves. I refuse to judge such matters." 16 And he threw them out of the courtroom. 17 The crowd then grabbed Sosthenes, the leader of the synagogue, and beat him right there in the courtroom. But Gallio paid no attention.
18 Paul stayed in Corinth for some time after that, then said good-bye to the brothers and sisters and went to nearby Cenchrea. There he shaved his head according to Jewish custom, marking the end of a vow. Then he set sail for Syria, taking Priscilla and Aquila with him. 19 They stopped first at the port of Ephesus, where Paul left the others behind. While he was there, he went to the synagogue to reason with the Jews.

Commentary on Acts 18:1-6
(Read Acts 18:1-6)
Though Paul was entitled to support from the churches he planted, and from the people to whom he preached, yet he worked at his calling. An honest trade, by which a man may get his bread, is not to be looked upon with contempt by any. It was the custom of the Jews to bring up their children to some trade, though they gave them learning or estates. Paul was careful to prevent prejudices, even the most unreasonable. The love of Christ is the best bond of the saints; and the communings of the saints with each other, sweeten labour, contempt, and even persecution. Most of the Jews persisted in contradicting the gospel of Christ, and blasphemed. They would not believe themselves, and did all they could to keep others from believing. Paul hereupon left them. He did not give over his work; for though Israel be not gathered, Christ and his gospel shall be glorious. The Jews could not complain, for they had the first offer. When some oppose the gospel, we must turn to others. Grief that many persist in unbelief should not prevent gratitude for the conversion of some to Christ.
Commentary on Acts 18:7-11
(Read Acts 18:7-11)
The Lord knows those that are his, yea, and those that shall be his; for it is by his work upon them that they become his. Let us not despair concerning any place, when even in wicked Corinth Christ had much people. He will gather in his chosen flock from the places where they are scattered Thus encouraged, the apostle continued at Corinth, and a numerous and flourishing church grew up.
Commentary on Acts 18:12-17
(Read Acts 18:12-17)
Paul was about to show that he did not teach men to worship God contrary to law; but the judge would not allow the Jews to complain to him of what was not within his office. It was right in Gallio that he left the Jews to themselves in matters relating to their religion, but yet would not let them, under pretence of that, persecute another. But it was wrong to speak slightly of a law and religion which he might have known to be of God, and which he ought to have acquainted himself with. In what way God is to be worshipped, whether Jesus be the Messiah, and whether the gospel be a Divine revelation, are not questions of words and names, they are questions of vast importance. Gallio spoke as if he boasted of his ignorance of the Scriptures, as if the law of God was beneath his notice. Gallio cared for none of these things. If he cared not for the affronts of bad men, it was commendable; but if he concerned not himself for the abuses done to good men, his indifference was carried too far. And those who see and hear of the sufferings of God's people, and have no feeling with them, or care for them, who do not pity and pray for them, are of the same spirit as Gallio, who cared for none of these things.
Commentary on Acts 18:18-23
(Read Acts 18:18-23)
While Paul found he laboured not in vain, he continued labouring. Our times are in God's hand; we purpose, but he disposes; therefore we must make all promises with submission to the will of God; not only if providence permits, but if God does not otherwise direct our motions. A very good refreshment it is to a faithful minister, to have for awhile the society of his brethren. Disciples are compassed about with infirmity; ministers must do what they can to strengthen them, by directing them to Christ, who is their Strength. Let us earnestly seek, in our several places, to promote the cause of Christ, forming plans that appear to us most proper, but relying on the Lord to bring them to pass if he sees good.
