5 When Silas and Timothy arrived from Macedonia, Paul was able to give all his time to preaching and teaching, doing everything he could to persuade the Jews that Jesus was in fact God's Messiah. 6 But no such luck. All they did was argue contentiously and contradict him at every turn. Totally exasperated, Paul had finally had it with them and gave it up as a bad job. "Have it your way, then," he said. "You've made your bed; now lie in it. From now on I'm spending my time with the other nations."
7 He walked out and went to the home of Titius Justus, a God-fearing man who lived right next to the Jews' meeting place. 8 But Paul's efforts with the Jews weren't a total loss, for Crispus, the meeting-place president, put his trust in the Master. His entire family believed with him. 9 One night the Master spoke to Paul in a dream: "Keep it up, and don't let anyone intimidate or silence you. 10 No matter what happens, I'm with you and no one is going to be able to hurt you. You have no idea how many people I have on my side in this city."

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.
