Acts 19:8-9

Acts 19:8-9 AMP

And he went into the synagogue and for three months spoke boldly, reasoning and arguing and persuading them about the kingdom of God. But when some were becoming hardened and disobedient [to the word of God], discrediting and speaking evil of the Way (Jesus, Christianity) before the congregation, Paul left them, taking the disciples with him, and went on holding daily discussions in the lecture hall of Tyrannus [instead of in the synagogue].
