Acts 12:10-11

¹⁰And going though the first and the second guard posts, they came to the iron gate which leads into the city, which was opened to them of its own accord; and going out, they went forward one street, and immediately the angel withdrew from him.

¹¹And Peter, having come to himself, said, “Now I know truly that the Lord has sent forth His angel, and has delivered me from the hand of Herod and from all the expectation of the Jews.”
