Acts 19:8-10 HCSB
Then he entered the synagogue and spoke boldly over a period of three months, engaging in discussion and trying to persuade them about the things of the kingdom of God. But when some became hardened and would not believe, slandering the Way in front of the crowd, he withdrew from them and met separately with the disciples, conducting discussions every day in the lecture hall of Tyrannus. And this went on for two years, so that all the inhabitants of Asia, both Jews and Greeks, heard the message about the Lord.
