Acts 12:11-12

When Peter came to his senses, he said, “Now I know for certain that the Lord has sent His angel and has rescued me from the hand of Herod and from all that the Jewish people were expecting [to do to me].” When he realized what had happened, he went to the house of Mary the mother of John, who was also called Mark, where many [believers] were gathered together and were praying continually [and had been praying all night].
