Acts 12:7-10

7And lo, an angel of [the] Lord came there, and a light shone in the prison: and having smitten the side of Peter, he roused him up, saying, Rise up quickly. And his chains fell off his hands.

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

9And going forth he followed [him] and did not know that what was happening by means of the angel was real, but supposed he saw a vision.

10And having passed through a first and second guard, they came to the iron gate which leads into the city, which opened to them of itself; and going forth they went down one street, and immediately the angel left him.
