Acts 19:8
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.
And he went into the synagogue,.... Of the Jews at Ephesus, for it seems to have been a private house, where he had met with the twelve baptized disciples, and had laid his hands on them; and these being Jews, as it seems most likely, by their having been baptized into John's baptism, the apostle went along with them to the synagogue on the sabbath day, as was his usual custom; having a very great desire, and an affectionate concern, for the welfare of his countrymen the Jews:
and spake boldly for the space of three months; that is, he used great freedom of speech, and showed much courage and intrepidity of mind, in preaching the Gospel at the synagogue every sabbath day as it returned, during this space of time; some manuscripts read, "three days":
disputing and persuading the things concerning the kingdom of God; the kingdom of the Messiah, the Gospel dispensation, the doctrines and ordinances of the Gospel, and the Gospel church state, often signified by the kingdom of God, and of heaven, in Scripture; and concerning the glory of a future state, the way and right unto it, and meetness for it; and these things he reasoned upon in such a strong and nervous manner, and made use of such powerful arguments, in proof and demonstration of them, as were very persuasive, and engaged many to believe them, and give their assent unto them.
