Acts 8:1-4 NLT

1 Saul was one of the official witnesses at the killing of Stephen. 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.)
3 Saul was going everywhere to devastate the church. He went from house to house, dragging out both men and women to throw them into jail.
4 But the believers who had fled Jerusalem went everywhere preaching the Good News about Jesus.
