Ch 8 v1Saul was one of the official witnesses at the killing of Stephen. 2. A great wave of persecution began that day, sweeping over the church in Jerusalem, and all the believers except the apostles fled into Judea and Samaria. 2(Some godly men came and buried Stephen with loud weeping.) 3Saul was going everywhere to devastate the church. He went from house to house, dragging out both men and women to throw them into jail. 4But the believers who had fled Jerusalem went everywhere preaching the Good News about Jesus. 5Philip, for example, went to the city of Samaria and told the people there about the Messiah. 6Crowds listened intently to what he had to say because of the miracles he did. 7Many evil spirits were cast out, screaming as they left their victims. And many who had been paralyzed or lame were healed. 8So there was great joy in that city.
The expansion from Jerusalem came mainly after Stephens death due to the persecution and people fleeing Jerusalem. The Bible say so.
LOL you read but cannot see. Pentecost was one of those holy days Jews were called to be in Jerusalem for at least once in a life time pilgrimage and, since it is 50 days after Passover, it makes sense they were "dwelling" and not living. Since they were Jews, if they were living there, why the reference to their countries of origin. They were there on a pilgrimage snipe, thus the reference to their homeland. Since they were from all over, it makes perfect sense they would stay for the both passover and pentecost.
But reading on down the chapter read v 43-47. Now they basically remained in Jerusalem till chapter 8 living among each other in a common community sharing property etc.
and you forget that among those 3000 were Jews who had their permanent residence in Jerusalem and Israel - not all were Jews living out of country.
Look at what transpired in chapter 8. The Apostiles were too later venture out as well.
And NO WHERE does it indicate that the persecution was the result of the Holy Spirit punishing the believers for not going out. Further, there is every reason to believe that others remained with the Apostles. So? The word was already moving out since Pentecost. The bible in no place links that persecution to chastisement from the Spirit.
