Acts 19:8-10

And he entered into the synagogue, and spake boldly for the space of three months, reasoning and persuading as to the things concerning the kingdom of God. But when some were hardened and disobedient, speaking evil of the Way before the multitude, he departed from them, and separated the disciples, reasoning daily in the school of Tyrannus. And this continued for the space of two years; so that all they that dwelt in Asia heard the word of the Lord, both Jews and Greeks.
