Acts 12:6-11

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, the angel of the Lord came upon him, and a light shone in the prison: and he smote Peter on the side, and raised him up, saying, Arise quickly. And his chains fell off from his hands. 8And the angel said to him, Gird thyself, and bind on thy sandals. And so he did. And he saith to him, Cast thy garment about thee, and follow me. 9And he went out, and followed him; and knew not that it was true which was done by the angel; but thought he saw a vision. 10When they were past the first and the second guard, they came to the iron gate that leadeth to the city; which opened to them of its own accord: and they went out, and passed on through one street; and immediately the angel departed from him. 11And when Peter had come to himself, he said, Now I know with certainty, 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.
