Jamieson, Fausset & Brown, on Acts 12:10

“And 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.”

“first and the second ward . . . the iron gate that leadeth unto the city--We can only conjecture the precise meaning of all this, not knowing the position of the prison. passed on through one street; and forthwith the angel departed from him--when he had placed him beyond pursuit. Thus "He disappointeth the devices of the crafty, so that their heads cannot perform their enterprise" (Job 5:12).”
