John Mark
Mark 14:70KJV·traditional attribution
And he denied it again. And a little after, they that stood by said again to Peter, Surely thou art one of them: for thou art a Galilaean, and thy speech agreeth thereto.
Matthew Henry Presbyterian
We have here the story of Peter's denying Christ. 1. It began in keeping at a distance from him. Peter had followed afar off (Mar 14:54), and now was beneath in the palace, at the lower end of the hall.
