Acts 12: 1 Now about that time Herod the king stretched out his hand to harass some from the church.
2 Then he killed James the brother of John with the sword.
3 And because he saw that it pleased the Jews, he proceeded further to seize Peter also. Now it was during the Days of Unleavened Bread.
4 So when he had arrested him, he put him in prison, and delivered him to four squads of soldiers to keep him, intending to bring him before the people after Passover.
5 Peter was therefore kept in prison, but constant prayer was offered to God for him by the church.
