Acts 12:10-11

¹⁰And passing through the first and the second ward, they came to the iron gate that leadeth to the city, which of itself opened to them. And going out, they passed on through one street: and immediately the angel departed from him.

¹¹And Peter coming to himself, said: Now I know in very deed, 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.
