Acts 8:1-4

Saul agreed with putting him to death. On that day a severe persecution broke out against the church in Jerusalem, and all except the apostles were scattered throughout the land of Judea and Samaria.  Devout men buried Stephen and mourned deeply over him. Saul,  however, was ravaging the church. He would enter house after house, drag off men and women, and put them in prison.  So those who were scattered went on their way preaching the word.
