When divers were hardened and believed not. — Better (the verb implying continuous action), when some were growing hardened and disobedient.
Spake evil of that way before the multitude. — Better, as before, of the way. (See Note on Acts 9:2.) The unbelieving Jews acted at Ephesus as at Thessalonica, and tried to wreak their hatred against St. Paul by stirring up suspicion among the Gentiles, especially, as before, among those of the lower class, who were always ready for a tumult.
Disputing daily in the school of one Tyrannus. — The Greek word for “school” had a somewhat interesting history. Originally meaning “leisure,” it was applied to leisure as bestowed on study, then, as here, to the place in which study was pursued; lastly, as in our phrase, “the school of Zeno or Epicurus,” as a collective term for the followers of a conspicuous teacher. In this case, it was probably a lecture-room which, as the private property of the owner, was lent or let to the Apostle.
Of the Tyrannus here mentioned nothing more is known with certainty, but the name is connected with one or two interesting coincidences that are more or less suggestive. Like its Latin equivalent, Rex it was not uncommon among the class of slaves or freed-men. It is found in the Columbarium of the household of Livia on the Appian Way, and as belonging to one who is described as a Medicus or physician. Both names and professions in this class were very commonly hereditary, and the hypothesis that this Tyrannus was also a physician, and that, as such, he may have known St. Luke, or, possibly, may have been among the Jews whom the decree of Claudius (Acts 18:2) had driven from Rome, and so shared the faith of Aquila and Priscilla, fits in with and explains the facts recorded. An unconverted teacher of philosophy or rhetoric was not likely to have lent his class-room to a preacher of the new faith. (See also Note on Acts 19:12.)
