17:23 When the keepers before the door found that Peter had escaped, they were seized with terror. It had been expressly stated that their lives would be required for the life of their charge, and because of this they had been especially vigilant. When the officers came for Peter, the soldiers were still at the door of the prison, the bolts and bars were still fast, the chains were still secured to the wrists of the two soldiers; but the prisoner was gone.
