Acts 12:7–9 (ESV) 7 And behold, an angel of the Lord stood next to him, and a light shone in the cell. He struck Peter on the side and woke him, saying, “Get up quickly.” And the chains fell off his hands. 8 And the angel said to him, “Dress yourself and put on your sandals.” And he did so. And he said to him, “Wrap your cloak around you and follow me.” 9 And he went out and followed him. He did not know that what was being done by the angel was real, but thought he was seeing a vision.
