Acts 12:3-7

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.

⁶And when Herod would have brought him forth, the same night Peter was sleeping between two soldiers, bound with two chains: and the keepers before the door kept the prison.

⁷And behold an angel of the Lord stood by him: and a light shined in the room: and he striking Peter on the side, raised him up, saying: Arise quickly. And the chains fell off from his hands.
