Acts 12:3-5

³And seeing that it pleased the Jews, he proceeded to take up Peter also. Now it was in the days of the Azymes.

⁴And when he had apprehended him, he cast him into prison, delivering him to four files of soldiers to be kept, intending, after the pasch, to bring him forth to the people.

⁵Peter therefore was kept in prison. But prayer was made without ceasing by the church unto God for him.
