Acts 19:8-9

Twentieth_Century(i) 8 Paul went to the Synagogue there, and for three months spoke out fearlessly, giving addresses and trying to convince his hearers, about the kingdom of God. 9 Some of them, however, hardened their hears and refused to believe, denouncing the Cause before the people. So Paul left them and withdrew his disciples, and gave daily addresses in the lecture-hall of Tyrannus.
