Chapter twelve accounts the death of the First Apostle James and the arrest of Peter. Herod wants to be popular among the people and has many guards to guard him. The biblke states that there were four squads of four guards. Doing the math, that means sixteen guards were guarding Peter to keep him in jail. He was shakled by “double chains”. Two chains are holding Peter in place and two guards are right next to him on each side. Two guards are right outside the door and the others are about the place. Sounds like he is heavily guarded. Does this have anything to do with the resurrection of Jesus and only the two at Jesus’ tomb? Who knows. Either way, Peter getting out is not a very likely prospect.
