Acts 18:7-11 NIV
Then Paul left the synagogue and went next door to the house of Titius Justus, a worshiper of God. Crispus, the synagogue leader, and his entire household believed in the Lord; and many of the Corinthians who heard Paul believed and were baptized. 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 in Corinth for a year and a half, teaching them the word of God.
