“So Paul left the synagogue and took the believers with him. Then he held daily discussions at the lecture hall of Tyrannus. This went on for the next two years, so that people throughout the province of Asia—both Jews and Greeks—heard the word of the Lord” (Acts 19:9-10 NLT).

PAUL RENTS A SCHOOL FOR CHURCH MEETINGS
Ephesus was one of the largest cities in the Roman Empire during the time of Paul. It was a strategically placed seaport city with a population of over 250,000. It became the new center of Paul’s missionary efforts. Some gospel work had already been done in Ephesus, but now Paul lay a foundation for one of the greatest churches of the first and second centuries. The people of Ephesus and the surrounding province were so open to the gospel that Paul was able to rent a school from a local named Tyrannus, where Paul preached and taught daily for over two years.
 
Our church rented schools for our meetings for 19 years before we purchased a property of our own. I’m not sure how long the church at Ephesus rented the school of Tyrannus, for Paul felt the call to head back out on his third missionary journey after two years. Perhaps they were still renting when Jesus had John send them a letter some years later (Rev. 2:1-7).
