Acts18v1to11.

After this, Paul left Athens and went to Corinth. There he met a Jew named Aquila, a native of Pontus, who had recently come from Italy with his wife Priscilla, because Claudius had ordered all the Jews to leave Rome. Paul went to see them, and because he was a tentmaker as they were, he stayed and worked with them. Every Sabbath he reasoned in the synagogue, trying to persuade Jews and Greeks.
When Silas and Timothy came from Macedonia, Paul devoted himself exclusively to preaching, testifying to the Jews that Jesus was the Christ. But when the Jews opposed Paul and became abusive, he shook out his clothes in protest and said to them, "Your blood be on your own heads! I am clear of my responsibility. From now on I will go to the Gentiles."
Then Paul left the synagogue and went next door to the house of Titius Justus, a worshipper of God. Crispus, the synagogue ruler, and his entire household believed in the Lord: and many of the Corinthians who heard him believed and were baptised.
One night the Lord spoke to Paul in a vision: "Do not be afraid; keep on speaking, do not be silent. For I am with you, and no-one is going to attack and harm you, because I have many people in this city." So Paul stayed for a year and a half, teaching them the word of God.
