5 And when both Silas and Timotheus came down from Macedonia, Paul was pressed in respect of the word, testifying to the Jews that Jesus was the Christ. 6 But as they opposed and spoke injuriously, he shook his clothes, and said to them, Your blood be upon your own head: I [am] pure; from henceforth I will go to the nations.
7 And departing thence he came to the house of a certain [man], by name Justus, who worshipped God, whose house adjoined the synagogue. 8 But Crispus the ruler of the synagogue believed in the Lord with all his house; and many of the Corinthians hearing, believed, and were baptised. 9 And the Lord said by vision in [the] night to Paul, Fear not, but speak and be not silent; 10 because I am with thee, and no one shall set upon thee to injure thee; because I have much 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.
