Acts of the Apostles 8:1, 3

Saul was one of the witnesses, and he agreed completely with 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 were scattered through the regions of Judea and Samaria.

But Saul was going everywhere to destroy the church. He went from house to house, dragging out both men and women to throw them into prison.
