Acts 19:8-10

8And he went into the synagogue, and spoke boldly for the space of three months, disputing and persuading the things concerning the kingdom of God. 9But when some were hardened, and believed not, but spoke evil of that way before the multitude, he departed from them, and separated the disciples, disputing daily in the school of one Tyrannus. 10And this continued for the space of two years; so that all they who dwelt in Asia heard the word of the Lord Jesus, both Jews and Greeks.
