Acts 12:10-11

¹⁰And when they had gone past the first and second watchmen they came to the iron door into the town, which came open by itself: and they went out and down one street; and then the angel went away.

¹¹And when Peter came to his senses he said, Now, truly, I am certain that the Lord has sent his angel and taken me out of the hands of Herod, against all the hopes of the Jews.
