Acts 19:6-10
Acts 19:6 (KJB)
And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.
In a symbolic gesture, the Apostle Paul had laid his hands on them and at the same moment the Holy Ghost came upon them which means they became saved at that very moment. Then immediately after they became saved they had started speaking with tongues and this was legitimate languages not the gibberish which is spewed forth in false tongue speaking churches of today. Along with the gift of languages, which was not given to them for self-exaltation, the purpose was to declare Godís word and that is what they did in prophesying. At this time there was no written New Testament books (except maybe the Book of James which is an early writing) so what they prophesied was messages they received from God. Now their message was complete because no longer was repentance to be done for itself but now it was done for the ministry of Christ in a personís life.
Acts 19:7 (KJB)
And all the men were about twelve.
It was a very small group with a number of about twelve but now Paul had some backup for his initial ministry in Ephesus. They could now get down to planning for the evangelization of Ephesus. They could at least go out two by two and although they may not know much at this time, they could at least be testimonies for what the Lord has done for them.
Acts 19:8 (KJB)
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.
When the next sabbath came around, Paul continued his custom going into the synagogue and bring them the true gospel. Paul was not one to withhold anything when speaking about the gospel. He went into the synagogue and spoke boldly about the gospel in contrast to the way the Gospel is presented today, almost with an apologetic tone. If one is presenting the Gospel, then they need to be bold in their assertion and presentation. This is what Paul did and why it got him into so much trouble while simultaneously convincing some in attendance and making converts to Christianity. People are put off when we make a really poor showing or a very soft presentation of the Gospel because hell is not going to be a soft place. The tenets of false religions must be answered and answered boldly and confidently. We have nothing to apologize for because we are bringing the truth, let the false religions apologize, because they are the liars.
Acts 19:9 (KJB)
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.
Hardened - Stubborn or resistant to change
It took a little longer in Ephesus for the hardened Jews to verbally show their opposition to the truth. They had become hardened to the truth and remained unconvinced that Jesus was their Messiah. They had begun to speak evil of Christianity and they started doing it to the multitudes of people, probably those who came to synagogue and than afterward in public places. Paul did not become discouraged because by this time, he had already come to expect opposition so he just departed from them and sought a place to bring the disciples where he could meet with them and then begin to explain the principles of Christianity more fully to them without any opposition. Paul had found a place where he could reason the true Gospel outside the synagogue. The school of Tyrannus was a philosophical school where no doubt Paul came up against the philosophy of all the ancient Greek philosophers. Paul had disputed in this school for two years which gave him a long time to establish a strong church in Ephesus. I am sure that he probably gained some of the students of Tyrannus. In this school, Jewish scribes would also instruct in the Law. It is not known if Tyrannus was one of the Jews who came from Rome by decree of Claudius requiring all Jews to leave Rome or if he was a pagan philosopher. Whatever he was, he heard the true Gospel for two full years.
Acts 19:10 (KJB)
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.
While Paul was probably in the school of Tyrannus by day, in the evening he would go to different homes and teach again. Since he did this for a period of two years, the true Gospel had begun permeating the entire area of Asia. The Jews as well as the Greeks heard the true Gospel. Probably many went to the school of Tyrannus to listen to the debates and probably many were won to Christ and then they brought others and the amount of disciples began to grow. Ephesus was like Corinth, it was a large center of trade and business, so there would have been many from various parts of Asia who would have been evangelized and when they became saved, they went back to their own homes and began evangelizing there.
