Acts 12:7-8, 11

And behold, an angel of the Lord stood by him, and a light shined in the cell: and he smote Peter on the side, and awoke him, saying, Rise up quickly. And his chains fell off from his hands. And the angel said unto him, Gird thyself, and bind on thy sandals. And he did so. And he saith unto him, Cast thy garment about thee, and follow me.

And when Peter was come to himself, he said, Now I know of a truth, that the Lord hath sent forth his angel and delivered me out of the hand of Herod, and from all the expectation of the people of the Jews.
