King Herod killed James and imprisoned Peter. He put Peter in a well-guarded prison. However, the Christian church prayed for Peter. While Peter was guarded at night, an angel of the Lord appeared. The angel told Peter to get dressed. Peter thought that this was a vision. The angel left Peter, so that Peter realized that it was the angel of the Lord. Once he escaped, he went to the house of Mary. A maid answered the door. She announced to the others that Peter was there. They wondered whether she was crazy? Peter continued knocking at the door. Then they let Peter in and he told them what had happened. The soldiers guarding Peter were upset because Peter escaped. King Herod had those guards killed.
