Acts 12:5-9

5So Peter was kept in prison, but the church was earnestly praying to God for him. 6The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance.

7Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. “Quick, get up!” he said, and the chains fell off Peter’s wrists. 8Then the angel said to him, “Put on your clothes and sandals.” And Peter did so. “Wrap your cloak around you and follow me,” the angel told him. 9Peter followed him out of the prison, but he had no idea that what the angel was doing was really happening; he thought he was seeing a vision.
