Acts 12:5-7

So Peter was kept in jail, but the church prayed earnestly to God for him. The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains. Other soldiers were guarding the door of the jail. Suddenly, an angel of the Lord stood there, and a light shined in the cell. The angel struck Peter on the side and woke him up. “Hurry! Get up!” the angel said. And the chains fell off Peter’s hands.
