Acts 12:4-12

And when he had taken him, he put him in prison, and delivered him to four quaternions of soldiers to guard him; intending after the Passover to bring him forth to the people. Peter therefore was kept in the prison: but prayer was made earnestly of the church unto God for him. And when Herod was about to bring him forth, the same night Peter was sleeping between two soldiers, bound with two chains: and guards before the door kept the prison. And behold, an angel of the Lord stood by him, and a light shined in the cell: and he smote Peter on the side, and awoke him, saying, Rise up quickly. And his chains fell off from his hands. And the angel said unto him, Gird thyself, and bind on thy sandals. And he did so. And he saith unto him, Cast thy garment about thee, and follow me. And he went out, and followed; and he knew not that it was true which was done by the angel, but thought he saw a vision. And when they were past the first and the second guard, they came unto the iron gate that leadeth into the city; which opened to them of its own accord: and they went out, and passed on through one street; and straightway the angel departed from him. And when Peter was come to himself, he said, Now I know of a truth, that the Lord hath sent forth his angel and delivered me out of the hand of Herod, and from all the expectation of the people of the Jews. And when he had considered the thing, he came to the house of Mary the mother of John whose surname was Mark; where many were gathered together and were praying.
