Acts 19 - Separation

Act 19:1    And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,

Act 19:7    And all the men were about twelve.

Act 19:8    And he went into the synagogue, and spake boldly for the space of three months, disputing and persuading the things concerning the kingdom of God.

Act 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.

John Gill writes...

he departed from them; the hardened, unbelieving, and blaspheming Jews, as being unworthy of the means of grace; he went out of their synagogue, and no more entered there: and separated the disciples; from them, the twelve disciples he had laid his hands on, and others who in this space of time, the space of three months, had been converted under his ministry; these he formed into a separate Gospel church state, as well as engaged them to quit the company and conversation of these blasphemers, and no more attend with them in their synagogue, that so they might not be infected and corrupted by them; a separation from such who contradict and blaspheme the truths and ordinances of the Gospel, is justifiable:

Act 19:10    And this continued by the space of two years; so that all they which dwelt in Asia heard the word of the Lord Jesus, both Jews and Greeks.
