Acts 12:3-5

³After he saw that this pleased the Jews, he proceeded to arrest Peter also. That was during the days of unleavened bread.

⁴After arresting him, he put him in prison, assigning him over to four squads of soldiers to guard him; he was intending to bring him to the people after the Passover.

⁵So Peter was kept in the prison, but prayer was made earnestly to God for him by those in the church.
