acts 19:9 But when divers were hardened, and believed not, but spake evil of that way before the multitude, he departed from them, and separated the disciples, disputing daily in the school of one Tyrannus. - Free Bible Online

      9. when divers--"some."
      were hardened, &c.--implying that others, probably a large number, believed.
      spake evil of that way before the multitude, he departed--from the synagogue, as at Corinth (Ac 18:7).
      and separated the disciples--withdrawing to a separate place of meeting, for the sake both of the converts already made, and the unsophisticated multitude.
      disputing--"discoursing" or "discussing."
      daily in the school--or lecture hall.
      of one Tyrannus--probably a converted teacher of rhetoric or philosophy.
