Acts 12:9-10

9So Peter followed the angel out of the prison. He was not sure that all these things were really happening to him. He thought that he might be dreaming.

10Peter and the angel walked past the first group of soldiers in the prison. Then they walked past the second group of soldiers. After that, they came to the big metal gate in the wall of the prison. The city was outside this gate. The gate opened by itself in front of them. So Peter and the angel went out of the prison through the gate. They walked together along one street and then, suddenly, the angel went away.
