Acts 12
6 Ref And when Herod was about to take him out, the same night Peter was sleeping in chains between two armed men, and the watchmen were keeping watch before the door of the prison.
7 Ref And a great light was seen shining in the room, and an angel of the Lord came to Peter and, touching him on his side so that he came out of his sleep, said, Get up quickly. And his chains came off his hands.
