Acts 12:7-11

Now behold, an angel of the Lord stood by him, and a light shone in the prison; and he struck Peter on the side and raised him up, saying, “Arise quickly!” And his chains fell off his hands. Then the angel said to him, “Gird yourself and tie on your sandals”; and so he did. And he said to him, “Put on your garment and follow me.” So he went out and followed him, and did not know that what was done by the angel was real, but thought he was seeing a vision. When they were past the first and the second guard posts, they came to the iron gate that leads to the city, which opened to them of its own accord; and they went out and went down one street, and immediately the angel departed from him. And when Peter had come to himself, he said, “Now I know for certain that the Lord has sent His angel, and has delivered me from the hand of Herod and from all the expectation of the Jewish people.”
