“And when Herod would have brought him forth, the same night Peter was sleeping between two soldiers, bound with two chains: and the keepers before the door kept the prison.”
King James Version (KJV)
12:6 Peter was sleeping - Easy and void of fear; between two soldiers - Sufficiently secured to human appearance.
Act 12:6 When Herod would have brought him forth. To execution, probably on the day after the passover week ended. The Jews thought that executions during this week were a desecration. Peter was sleeping between two soldiers, bound with two chains. The Roman method was adopted. He was chained to the soldiers who slept on each side of him, while the other two soldiers of the watch stood before the prison door. These precautions were taken for fear of a rescue.
