Acts 19:9

"But when divers were hardened, speaking evil of the way." They might well call it "the way"; this was indeed the way, that led into the kingdom of heaven. "He departed from them, and separated the disciples, disputing daily in the school of one Tyrannus." He put a stop to their evil-speaking: he did not wish to kindle their envy. Hence let us also learn not to put ourselves in the way of evil-speaking men, but to depart from them: he did not speak evil, when himself evil spoken of. "He disputed daily," and by this gained the many.

"And having entered in to the synagogue," etc. But why did he speak boldly? It means, he was ready to confront dangers, and disputed more openly, not veiling the doctrines. "But when some were hardened, and spake evil of the way, having departed from them, he separated the disciples." He put a stop, it means, to their evil-speaking: he did not wish to kindle their envy, nor to bring them into more contention. Hence let us also learn not to put ourselves in the way of evil-speaking men, but to depart from them: he did not speak evil, when himself evil spoken of. "He disputed daily," and by this gained the many, that, being evil intreated and evil spoken of, he did not utterly break away from them, and keep aloof. The evil-speakers are defeated. They calumniated the doctrine itself; therefore so as neither to rouse the disciples to wrath, nor disturb them, he withdrew, showing that everywhere alike they repel salvation from them.

He separated the disciples, daily disputing in the school of a certain Tyrannus. This happened for three years, etc. At this time, while Paul was staying in Ephesus, it is said that he wrote the first letter to the Corinthians, in which he also mentions …

Luke calls Christ "the Way," of Whom it is also said that He is the way (see John 14:6). Or else he calls "the way" the true faith which Paul preached. And by the words "he separated the disciples," the instruction is given that those …

The way - The Christian way of worshipping God. He departed - Leaving them their synagogue to themselves. Discoursing daily - Not on the Sabbath only, in the school of one Tyrannus - Which we do not find was any otherwise consecrated, than by preaching the Gospel there.

But when divers were hardened and believed not,....

When divers were hardened - Τινες, When some of them were hardened; several no doubt felt the power of Divine truth, and yielded consent. Our term divers, one of the most bald in our language, has too general a meaning for this place. Behold the effect of the word of God! It is a savour of life unto life, or death unto death, according as it is received or rejected. The twelve men mentioned above received it affectionately, and they were made partakers of the Holy Ghost; the others were hardened, for they refused to believe; and they calumniated the doctrine, and became Satan’s preachers among the multitude, to prejudice them against Christ and his religion. Separated the disciples - Paul, and those converted under his ministry, had doubtless been in the habit of attending public worship in the synagogue: but, on the persecuting conduct of these Jews; he and his converts wholly withdrew from the synagogue, and took a place for themselves; and constantly afterwards held their own meetings at a school room, which they hired no doubt for the purpose. The school of one Tyrannus - For σχολῃ, the school, one MS. has συναγωγῃ, the synagogue; and, for Tyrannus, some have Tyrannios. Some have considered the original word as being an epithet, rather than the name of a person; and think that a prince or nobleman is intended, because τυραννος, tyrant, is taken in this sense: but this is a most unlikely conjecture. It appears that the person in question was a schoolmaster, and that he lent or hired his room to the apostles; and that they preached daily in it to as many, both Jews and Gentiles, as chose to attend. It is very likely that Tyrannus was a Jew, and was at least well affected to the Christian cause; for we have many proofs that individuals among them kept schools for the instruction of their youth; besides the schools or academies kept by the more celebrated rabbins.
