Acts 19:8

Paul preaches to the Jews first and afterwards to the Gentiles. The Word of God prevails mightily

8. And he entered into the synagogue As the incident of John's disciples is mentioned before anything else, it seems likely that St Paul found them among the few Christian brethren in Ephesus, and began his teaching of them before he commenced his visits to the synagogue.

and spake boldly for the space of three months Going there, that is, on all occasions of religious service, and so giving to his brethren of Israel a full opportunity of hearing all his reasoning, and inquiring whether what he taught was in accordance with the Scriptures. The abiding a longer time with them, which they had asked for (Acts 18:20) on his previous visit, does not seem to have gained him more adherents among the Jews. Perhaps he had noticed when the request was made that it was not with great fervour. Otherwise, it is not like the Apostle to pass by an opened door.

disputing[Better, reasoning] and persuading the things concerning the kingdom of God The Rev. Ver.has improved the translation in "reasoning," but the italic "as to" before "the things" is needless. The first participle is the same word as in Acts 17:2, and though "from the Scriptures" is not added here as there, we may surely understand it, and that the persuasion spoken of afterwards was no greater display of gentleness than the Apostle used at other times.
