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.
But when divers (or 'certain') were hardened, and believed not - implying, however, that others, and probably a considerable number, believed,
But spake evil of that way, х kakologountes (G2551) teen (G3588) hodon (G3598)] - 'calumniating' or 'speaking ill of the way' (see the note at Acts 9:2),
Before the multitude, he departed from them - just as he had done at Corinth (Acts 18:7),
And separated the disciples - withdrawing to a separate place of meeting, for the sake both of the converts already made, that he might be able to confirm and build them up, and of the unprejudiced multitude, that they might no longer be poisoned by a systematic and determined opposition to the truth.
Disputing (or 'discoursing') daily in the school (or 'lecture-room') of [one] Tyrannus. (The word "one" - omitted by Lachmann, Tishendorf, and Tregelles-is probably not genuine.) The attempt made by Meyer to make it probable that this Tyrannus was a Jew, and his school of a rabbinical character, is not successful. The almost universal opinion, that (whether converted or not) he was one of those Greek teachers of rhetoric or philosophy, who opened schools in all the principal cities of Greece and Roman Asia, has everything to confirm it.
