Acts
King James Version (KJV)

“And he went into the synagogue, and spake boldly for the space of three months, disputing and persuading the things concerning the kingdom of God.”
King James Version (KJV)
Ac 19:8 He went into the synagogue. Once before he had spoken in it, on his former missionary journey (Ac 18:19,20). Now for three months of the three years spent in Ephesus he occupies the same pulpit. These three years were comparatively quiet, but among the most successful of Paul's missionary career. About seventeen years of busy toil had now passed since his conversion.
