Acts 19:8, 9, 10

Paul went into the synagogue and for three months spoke boldly with the people, holding discussions with them and trying to convince them about the Kingdom of God.

But some of them were stubborn and would not believe, and before the whole group they said evil things about the Way of the Lord. So Paul left them and took the believers with him, and every day he held discussions in the lecture hall of Tyrannus.

This went on for two years, so that all the people who lived in the province of Asia, both Jews and Gentiles, heard the word of the Lord.
