Peter's at the Door, a Teter at the Door.

Peter followed him out of the prison, but he had no idea that what the angel was doing was really happening. They passed the first and second guards, the iron gate leading to the city and opened for them by itself. When they walked the length of one street, suddenly the angel left him. Then peter came to himself and said, now i know. Now i know without a doubt, that the lord has sent his angel and rescued me from herod's clutches.
