Acts of the Apostles 12:9-15

So Peter left the cell, following the angel. But all the time he thought it was a vision. He didn’t realize it was actually happening. They passed the first and second guard posts and came to the iron gate leading to the city, and this opened for them all by itself. So they passed through and started walking down the street, and then the angel suddenly left him. Peter finally came to his senses. “It’s really true!” he said. “The Lord has sent his angel and saved me from Herod and from what the Jewish leaders had planned to do to me!” When he realized this, he went to the home of Mary, the mother of John Mark, where many were gathered for prayer. He knocked at the door in the gate, and a servant girl named Rhoda came to open it. When she recognized Peter’s voice, she was so overjoyed that, instead of opening the door, she ran back inside and told everyone, “Peter is standing at the door!” “You’re out of your mind!” they said. When she insisted, they decided, “It must be his angel.”
