Acts 12:9

6 And 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.

7 And 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.

8 And the angel said to him: Gird thyself and put on thy sandals. And he did so. And he said to him: Cast thy garment about thee and follow me,

9 And going out, he followed him. And he knew not that it was true which was done by the angel: but thought he saw a vision.

10 And passing through the first and the second ward, they came to the iron gate that leadeth to the city which of itself opened to them. And going out, they passed on through one street. And immediately the angel departed from him.

11 And Peter coming to himself, said: Now I know in very deed that the Lord hath sent his angel and hath delivered me out of the hand of Herod and from all the expectation of the people of the Jews.

12 And considering, he came to the house of Mary the mother of John, who was surnamed Mark, where many were gathered together and praying.
