5 When Silas and Timothy had come from Macedonia, Paul was compelled by the Spirit, and testified to the Jews that Jesus is the Christ. 6 But when they opposed him and blasphemed, he shook his garments and said to them, "Your blood be upon your own heads; I am clean. From now on I will go to the Gentiles."
7 And he departed from there and entered the house of a certain man named Justus, one who worshiped God, whose house was next door to the synagogue. 8 Then Crispus, the ruler of the synagogue, believed on the Lord with all his household. And many of the Corinthians, hearing, believed and were baptized. 9 Now the Lord spoke to Paul in the night by a vision, "Do not be afraid, but speak, and do not keep silent; 10 for I am with you, and no one will attack you to hurt you; for I have many people 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.
